Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply
when operating the device outside of its rated operating conditions.
If Military- or Aerospace-specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability
and specifications.
The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal
resistance, RθJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated
using:
TJ(MAX) - TA
P(MAX) =
(4)
(5)
RqJA
The value of RθJA for the SOT-23 package is 220°C/W. Exceeding the maximum allowable power dissipation will cause excessive die
temperature, and the regulator will go into thermal shutdown.
If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2980-N output must be diode-clamped
to ground.
The output PNP structure contains a diode between the VIN and VOUT terminals that is normally reverse-biased. Reversing the polarity
from VIN to VOUT will turn on this diode (See Reverse Current Path).

7 Detailed Description
7.1 Overview
The LP2980-N is a 50-mA, fixed-output voltage regulator designed specifically to meet the requirements of
battery-powered applications. Available in output voltages from 2.5 V to 5 V, the device has an output tolerance
of 1% for the A grade (1.0% for the non-A version). Using an optimized VIP (Vertically Integrated PNP) process,
the LP2980-N contains these features to facilitate battery-powered designs:
• Fixed 5-V, 4.7-V, 3.3-V, 3-V, and 2.5-V output versions
• Very high accuracy 1.23-V reference
• Low-dropout voltage, typical dropout of 120 mV at 150-mA load current and 7 mV at 1-mA load
• Low ground current, typically 370 μA at 150-mA load and 80 μA at 1-mA load
• A sleep mode feature is available, allowing the regulator to consume only 1 µA typically when the ON/OFF
pin is pulled low.
• Overtemperature protection and overcurrent protection circuitry is designed to safeguard the device during
unexpected conditions.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 Multiple Voltage Options
To meet the different application requirements, the LP2980-N provides multiple fixed output options from 2.5 V to
5 V.
7.3.2 High-Accuracy Output Voltage
With special careful design to minimize all contributions to the output voltage error, the LP2980-N distinguishes
itself as a very high-accuracy output voltage micropower LDO. This includes a tight initial tolerance (0.5%
typical), extremely good line regulation (0.007%/V typical), and a very low output voltage temperature coefficient,
making the part an ideal low-power voltage reference.
7.3.3 Ultra-Low-Dropout Voltage
Generally speaking, the dropout voltage often refers to the voltage difference between the input and output
voltage (VDO = VIN – VOUT), where the main current pass-FET is fully on in the ohmic region of operation and is
characterized by the classic RDS(ON) of the FET. VDO indirectly specifies a minimum input voltage above the
nominal programmed output voltage at which the output voltage is expected to remain within its accuracy
boundary.

SNOS733N – APRIL 2000 – REVISED DECEMBER 2014

Feature Description (continued)
7.3.4 Low Ground Current
LP2980-N uses a vertical PNP process which allows for quiescent currents that are considerably lower than
those associated with traditional lateral PNP regulators, typically 370 μA at 150-mA load and 80 μA at 1-mA load.
7.3.5 Sleep Mode
When pulling the ON/OFF pin to low level, LP2980-N will enter sleep mode, and less than 1-μA quiescent current
is consumed. This function is designed for the application which needs a sleep mode to effectively enhance
battery life cycle.
7.3.6 Short-Circuit Protection (Current Limit)
The internal current-limit circuit is used to protect the LDO against high-load current faults or shorting events. The
LDO is not designed to operate in a steady-state current limit. During a current-limit event, the LDO sources
constant current. Therefore, the output voltage falls when load impedance decreases. If a current limit occurs
and the resulting output voltage is low, excessive power may be dissipated across the LDO resulting in a thermal
shutdown of the output. A foldback feature limits the short-circuit current to protect the regulator from damage
under all load conditions. If OUT is forced below 0 V before EN goes high and the load current required exceeds
the foldback current limit, the device may not start up correctly.
7.3.7 Thermal Protection
The LP2980-N contains a thermal shutdown protection circuit to turn off the output current when excessive heat
is dissipated in the LDO. The thermal time-constant of the semiconductor die is fairly short, and thus the output
cycles on and off at a high rate when thermal shutdown is reached until the power dissipation is reduced. The
internal protection circuitry of the LM2980-N is designed to protect against thermal overload conditions. The
circuitry is not intended to replace proper heat sinking. Continuously running the device into thermal shutdown
degrades its reliability.
7.4 Device Functional Modes
7.4.1 Operation with VOUT(TARGET) + 1 V ≤ VIN < 16 V
The device operates if the input voltage is equal to, or exceeds, VOUT(TARGET) + 0.6 V. At input voltages below
the minimum VIN requirement, the device does not operate correctly and output voltage may not reach target
value.
7.4.2 Operation With ON/OFF Control
If the voltage on the ON/OFF pin is less than 0.18 V, the device is disabled and the shutdown current does not
exceed 1 μA. Raising ON/OFF above 1.6 V initiates the startup sequence of the device.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LP2980-N is a linear voltage regulator operating from 2.1 V to 16 V on the input and regulates voltages
between 2.5 V to 5 V with 0.5% accuracy and 50-mA maximum output current. Efficiency is defined by the ratio
of output voltage to input voltage because the LP2980-N is a linear voltage regulator. To achieve high efficiency,
the dropout voltage (VIN – VOUT) must be as small as possible, thus requiring a very-low-dropout LDO.
Successfully implementing an LDO in an application depends on the application requirements. If the
requirements are simply input voltage and output voltage, compliance specifications (such as internal power
dissipation or stability) must be verified to ensure a solid design. If timing, startup, noise, power supply rejection
ratio (PSRR), or any other transient specification is required, then the design becomes more challenging. This
section discusses the implementation and behavior of the LP2980-N LDO.
8.2 Typical Application
*ON/OFF input must be actively terminated. Tie to VIN if this function is not to be used.
**Minimum output capacitance is 1 μF to ensure stability over full load current range. More capacitance provides
superior dynamic performance and additional stability margin (see Output Capacitor Recommendation).

8.2.2 Detailed Design Procedure
At 50-mA loading, the dropout of the LP2980-N has 225-mV maximum dropout over temperature, thus an 1700mV headroom is sufficient for operation over both input and output voltage accuracy. The efficiency of the
LP2980-N in this configuration is VOUT / VIN = 66.7%. To achieve the smallest form factor, the SOT23 package is
selected. Input and output capacitors are selected in accordance with the Output Capacitor Recommendation
section. With an efficiency of 66.7% and a 50-mA maximum load, the internal power dissipation is 85 mW, which
corresponds to a 14.9°C junction temperature rise for the SOT23 package. With an 85°C maximum ambient
temperature, the junction temperature is at 99.9°C.
8.2.2.1 Output Capacitor Recommendation
Like any low-dropout regulator, the LP2980-N requires an output capacitor to maintain regulator loop stability.
This capacitor must be selected to meet the requirements of minimum capacitance and equivalent series
resistance (ESR) range. It is not difficult to find capacitors which meet the criteria of the LP2980-N, as the
acceptable capacitance and ESR ranges are wider than for most other LDOs.
In general, the capacitor value must be at least 1 μF (over the actual ambient operating temperature), and the
ESR must be within the range indicated in Figure 31, Figure 32, and Figure 33. It should be noted that, although
a maximum ESR is shown in these figures, it is very unlikely to find a capacitor with an ESR that high.
8.2.2.1.1 Tantalum Capacitors
Surface-mountable solid tantalum capacitors offer a good combination of small physical size for the capacitance
value, and an ESR in the range needed by the LP2980-N.
The results of testing the LP2980-N stability with surface-mount solid tantalum capacitors show good stability
with values of at least 1 μF. The value can be increased to 2.2 μF (or more) for even better performance,
including transient response and noise.
Small value tantalum capacitors that have been verified as suitable for use with the LP2980-N are shown in
Table 1. Capacitance values can be increased without limit.
8.2.2.1.2 Aluminum Electrolytic Capacitors
Although probably not a good choice for a production design, because of relatively large physical size, an
aluminum electrolytic capacitor can be used in the design prototype for an LP2980-N regulator. A value of at
least 1 μF should be used, and the ESR must meet the conditions of Figure 31, Figure 32, and Figure 33. If the
operating temperature drops below 0°C, the regulator may not remain stable, as the ESR of the aluminum
electrolytic capacitor will increase and may exceed the limits indicated in Figure 31, Figure 32, and Figure 33.

8.2.2.1.3 Multilayer Ceramic Capacitors
Surface-mountable multilayer ceramic capacitors may be an attractive choice because of their relatively small
physical size and excellent RF characteristics. However, they sometimes have ESR values lower than the
minimum required by the LP2980-N, and relatively large capacitance change with temperature. The
manufacturer's data sheet for the capacitor should be consulted before selecting a value.
Test results of LP2980-N stability using multilayer ceramic capacitors show that a minimum value of 2.2 μF is
usually needed for the 5-V regulator. For the lower output voltages, or for better performance, a higher value
should be used, such as 4.7 μF.
Multilayer ceramic capacitors that have been verified as suitable for use with the LP2980-N are shown in
Table 2.

8.2.2.2 Reverse Current Path
The internal PNP power transistor used as the pass element in the LP2980-N has an inherent diode connected
between the regulator output and input. During normal operation (where the input voltage is higher than the
output) this diode is reverse biased (see Figure 34).
VIN
VOUT
PNP
GND
Figure 34. LP2980-N Reverse Current Path
However, if the input voltage is more than a VBE below the output voltage, this diode will turn on and current will
flow into the regulator output. In such cases, a parasitic SCR can latch which will allow a high current to flow into
the VIN pin and out the ground pin, which can damage the part.
The internal diode can also be turned on if the input voltage is abruptly stepped down to a voltage which is a VBE
below the output voltage.
In any application where the output voltage may be higher than the input voltage, an external Schottky diode
must be connected from VIN to VOUT (cathode on VIN, anode on VOUT, see Figure 35), to limit the reverse voltage
across the LP2980-N to 0.3 V (see Absolute Maximum Ratings).

8.2.2.3 ON/OFF Input Operation
The LP2980-N is shut off by pulling the ON/OFF input low, and turned on by driving the input high. If this feature
is not to be used, the ON/OFF input should be tied to VIN to keep the regulator on at all times (the ON/OFF input
must not be left floating).
To ensure proper operation, the signal source used to drive the ON/OFF input must be able to swing above and
below the specified turn-on and turn-off voltage thresholds which ensure an ON or OFF state (see Electrical
Characteristics).
The ON/OFF signal may come from either a totem-pole output, or an open-collector output with a pull-up resistor
to the LP2980-N input voltage or another logic supply. The high-level voltage may exceed the LP2980-N input
voltage, but must remain within the Absolute Maximum Ratings for the ON/OFF pin.

It is also important that the turn-on and turn-off voltage signals applied to the ON/OFF input have a slew rate that
is greater than 40 mV/μs.
NOTE
The regulator shutdown function will not operate correctly if a slow-moving signal is used
to drive the ON/OFF input.
8.2.2.4 Increasing Output Current
The LP2980-N can be used to control higher-current regulators, by adding an external PNP pass transistor. With
the PNP transistors shown in Figure 36, the output current can be as high as 400 mA, as long as the input
voltage is held within the Safe Operation Boundary Curves shown below in Figure 37.
To ensure regulation, the minimum input voltage of this regulator is 6 V. This headroom is the sum of the VBE of
the external transistor and the dropout voltage of the LP2980-N.
Notes:
1. Drive this input with a logic signal (see ON/OFF Input Operation). If the shutdown function is not to be used,
tie the ON/OFF pin directly to the VIN pin.
2. Recommended devices (other PNP transistors can be used if the current gain and voltage ratings are
similar).
3. Capacitor is required for regulator stability. Minimum size is shown, and may be increased without limit.
4. Increasing the output capacitance improves transient response and increases phase margin.
5. Maximum safe input voltage and load current are limited by power dissipation in the PNP pass transistor and
the maximum ambient temperature for the specific application. If a TO-92 transistor such as the MPS2907A
is used, the thermal resistance from junction-to-ambient is 180°C/W in still air.
Assuming a maximum allowable junction temperature of 150°C for the MPS2907A device, the following curves
show the maximum VIN and IL values that may be safely used for several ambient temperatures.

Figure 37. Safe Operation Boundary Curves for Figure 36
With limited input voltage range, the LP2980-N can control a 3.3-V, 3-A regulator with the use of a high currentgain external PNP pass transistor as shown in Figure 38. If the regulator is to be loaded with the full 3 A, heat
sinking will be required on the pass transistor to keep it within its rated temperature range. See Figure 39. For
best load regulation at the high load current, the LP2980-N output voltage connection should be made as close
to the load as possible.
Although this regulator can handle a much higher load current than can the LP2980-N alone, it can be shut down
in the same manner as the LP2980-N. When the ON/OFF control is brought low, the converter will be in
shutdown, and will draw less than 1 μA from the source.
Notes:
1. Drive this input with a logic signal (see ON/OFF Input Operation). If the shutdown function is not to be used,
tie the ON/OFF pin directly to the VIN pin.
2. Capacitor is required for regulator stability. Minimum size is shown, and may be increased without limit.
3. Increasing the output capacitance improves transient response and increases phase margin.
4. A heatsink may be required for this transistor. The maximum allowable value for thermal resistance of the
heatsink is dependent on ambient temperature and load current (see curves in Figure 39). Once the value is
obtained from the graph, a heatsink must be selected which has a thermal resistance equal to or lower than
this value. If the value is above 60°C/W, no heatsink is required (the TO-220 package alone will safely
dissipate this).
For these curves, a maximum junction temperature of 150°C is assumed for the pass transistor. The case-toheatsink attachment thermal resistance is assumed to be 1.5°C/W. All calculations are for 5.5-V input voltage
(which is worst-case for power dissipation).

9 Power Supply Recommendations
The LP2980-N is designed to operate from an input voltage supply range between 2.1 V and 16 V. The input
voltage range provides adequate headroom for the device to have a regulated output. This input supply must be
well regulated. If the input supply is noisy, additional input capacitors with low ESR can help improve the output
noise performance.
10 Layout
10.1 Layout Guidelines
For best overall performance, place all circuit components on the same side of the circuit board and as near as
practical to the respective LDO pin connections. Place ground return connections to the input and output
capacitors, and to the LDO ground pin as close to each other as possible, connected by a wide, component-side,
copper surface. The use of vias and long traces to create LDO circuit connections is strongly discouraged and
negatively affects system performance. This grounding and layout scheme minimizes inductive parasitics, and
thereby reduces load-current transients, minimizes noise, and increases circuit stability. A ground reference
plane is also recommended and is either embedded in the PCB itself or located on the bottom side of the PCB
opposite the components. This reference plane serves to assure accuracy of the output voltage, shield noise,
and behaves similar to a thermal plane to spread (or sink) heat from the LDO device. In most applications, this
ground plane is necessary to meet thermal requirements.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
