Description
The LDO40L is a 400 mA LDO regulator, designed for being used in severe automotive environments.
Low quiescent current makes it suitable for applications permanently connected to battery. This feature is especially critical when electronic modules remain in active mode when ignition is off.
The LDO40L embeds protection functions, such as: current limit and thermal shutdown.
The extended input voltage range, low drop voltage and low quiescent current features make it suitable also for low power industrial and consumer applications.

Application information
Application information
Operating input voltage
The LDO40L is a low-dropout linear voltage regulator equipped with a low-R
DS-(on)
P-channel MOSFET used as a pass-element. The device internal circuits are able to start with an input voltage as low as 3.5 V, whatever is the
nominal output voltage (see Figure 22. Output voltage vs. input voltage (no load)
. Defined the desired output voltage V
OUT-NOM
, the minimum input voltage V
IN-MIN
needed to fully bias the pass-element, is
V
IN-MIN
= V
OUT-NOM
+ V
DROP
. This allows to exit the dropout condition and achieve output voltage regulation.
and tolerance versus line and load changes is achieved for the highest input voltage among V
IN-MIN
= V
OUT-NOM
+ 1 V and V
IN-MIN
= 5 V .
At input voltages lower than V
IN-MIN
= (V
OUT-NOM
+ V
DROP
) the regulator enters dropout condition, regulation is not guaranteed and the output voltage tracks the input except for a voltage depending on the load current (I
OUT
) and the pass-element resistance (see
Figure 22. Output voltage vs. input voltage (no load)
. This tracking behavior can be useful during cold crank conditions.
Output voltage adjustment
The LDO40LY is available in fixed and adjustable output voltage versions. The latter option is usually chosen when the output voltage has to be set to non-standard values. In the adjustable version, the output voltage can be set from 2.5 V up to 11 V, by connecting a resistor divider between the ADJ pin and the output.
The architecture of the LDO40LY features a precise bandgap reference, which generates a fixed voltage V
REF
=
1.2 V between V
OUT
and ADJ terminals (refer to Figure 2. Block diagram, adjustable version
and Figure 5. Typical application diagram (adjustable versions)
). When the R1-R2 resistor divider is connected, a fixed current is generated through the divider. Since the contribution of current sourced by the ADJ pin is negligible (few tens of nA), the resulting output voltage is obtained by using the following equation:
(1) VOUT = VREF 1 + R2/R1 , witℎ VREF = 1.2V typ.
In order to guarantee a correct regulation, the resistor divider must be calculated for an output voltage of min.
2.5 V.
Output voltage sense pin
In the DFN6 package on pin 5, an additional V
SENSE
connection is available. This pin must not be left floating, since it is necessary for a correct sensing of the output voltage. It can be either connected to the load in a remotesensing configuration, or directly shorted to the V
OUT
pin (pin 4, refer to
Figure 4. Typical application diagram
(fixed versions) and Figure 5. Typical application diagram (adjustable versions) ).
Protection features
The device is self-protected from short-circuits and overtemperature events.
In case of strong overload or short-circuit on the output, the output current is limited to a value of typically 1.5 A and kept constant even when the load impedance is zero. If the overload persists, the temperature on the internal die rises, until the thermal protection is triggered, which happens when the junction temperature reaches 175 °C.
The device is subsequently shut down. As soon as the junction temperature falls again below 150 °C the device re-starts.
Even if the above described protections are able to keep the device safe in the worst cases, a correct thermal design of the application is recommended, according to the operating ambient temperature and the maximum power dissipation allowed by the chosen package. In order to calculate the maximum power that the device can dissipate, keeping the junction temperature below T
J-OP
= 125 °C, the following formula is used:
PDMAX = 125 − TAMB / RTHJ − A
The power dissipation on the device is calculated as P
D
= (V
IN
- V
OUT
) x I
OUT
.

Enable pin
Enable pin
The enable function allows the LDO output to be enabled/disabled. The regulator is turned on in case the pin EN is connected to a voltage higher than V
EN-H
, the LDO can be turned off if the voltage on EN pin is lower than
V
EN-L
.
No internal pull-up / pull-down is present on the EN pin, therefore it must not be left floating in the application.
Input and output capacitors
The LDO40LY requires external capacitors to ensure the regulator control loop stability.
A capacitor with a minimum value of 1 μF is required on at the input port of the LDO40LY.
This capacitor must be located as close as possible to the input pin of the device and returned to a clean analog ground. Good quality ceramic capacitors are suggested.
The device control loop is designed to be stable with good quality ceramic capacitors (such as: X5R/X7R types) with a minimum capacitance of 1 μF and equivalent series resistance in the [5 mΩ – 12 Ω] range. There is no
upper limit to the output capacitance. Figure 27. Stability plan
shows the stability plan tested on real capacitors, up to 10 µF. A value of 4.7 μF is suitable for the majority of applications, improving dynamic response and minimizing the risk of ringing and oscillations. It is important to highlight that the output capacitor must maintain its capacitance and ESR in the stable region over the full operating temperature, load and input voltage ranges, to assure stability. Therefore, capacitance and ESR variations must be taken into account in the design phase to ensure the device works in the expected stability region. There is no maximum limit to the output capacitance, provided that the above conditions are respected.
