MAX15027/MAX15028
1.425V to 3.6V Input, 1A Low-Dropout
Regulators with BIAS Input
General Description
Features
The MAX15027/MAX15028 low-dropout linear regulators
operate from input voltages as low as 1.425V and deliver
up to 1A of continuous output current with a typical
dropout voltage of only 75mV. The output voltage is
adjustable from 0.5V to VIN and is ±2% accurate over load
and line variations, from -40°C to +125°C. The MAX15028
features a BIAS input of 3V to 5.5V from an always-on
power supply. The BIAS input current is reduced down to
less than 2µA during shutdown.
These regulators use small, 1µF ceramic input capacitors and 4.7µF ceramic output capacitors to deliver 1A
output current. High bandwidth provides excellent transient response and limits the output voltage deviation to
15mV for a 500mA load step, with only a 4.7µF ceramic
output capacitor, and the voltage deviations can be
reduced further by increasing the output capacitor.
These devices offer a logic-controlled shutdown input
to reduce input current (IIN) consumption down to less
than 5.5µA in standby mode. Other features include a
soft-start to reduce inrush current, short-circuit protection, and thermal-overload protection.
The MAX15028 features a BIAS input allowing a secondary supply to keep the LDO’s internal circuitry alive
if the voltage on IN goes to 0V. Both devices are fully
specified from -40°C to +125°C and are available in a
10-pin thermally enhanced TDFN package (3mm x
3mm) that includes an exposed pad for optimal power
dissipation. For a 500mA version of these LDOs, refer
to the MAX15029/MAX15030 data sheet.

Detailed Description
The MAX15027/MAX15028 low-dropout linear regulators operate from input voltages as low as 1.425V and
deliver up to 1A of continuous output current with a
maximum dropout voltage of only 225mV.
The MAX15028 operates with an input voltage as low
as 1.425V if the bias voltage (VBIAS) of 3V to 5.5V is
available. The power is applied at IN while the control
is provided through BIAS input. The current drawn by
BIAS is negligible when the LDO goes into shutdown.
This feature is especially useful in automotive applica-
www.maximintegrated.com
tions where the BIAS input is derived from an alwayson LDO that expects to provide minimal power during
the key-off condition.
The pMOS output stage can be driven from input voltages down to +1.425V without sacrificing stability or
transient performance. The output voltage of all the
regulators is adjustable from 0.5V to VIN and is ±2%
accurate over load and line variations, from -40°C to
+125°C. Since these regulators have a pMOS output
device, supply current is not a significant function of
load or input headroom.

MAX15027/MAX15028
1.425V to 3.6V Input, 1A Low-Dropout
Regulators with BIAS Input
Internal p-Channel Pass Transistor
Shutdown Mode
The MAX15027/MAX15028 feature a 75mΩ (typ)
p-channel MOSFET pass transistor. Unlike similar
designs using pnp pass transistors, p-channel MOSFETs
require no base drive, reducing quiescent current.
pnp-based regulators also waste considerable current
in dropout when the pass transistor saturates and use
high base-drive currents under large loads. The
MAX15027/MAX15028 do not suffer from these problems and consume only 275µA (typ) of quiescent current under heavy loads, as well as in dropout.
The MAX15027/MAX15028 include an enable input. To
shut down the IC, drive EN low. In shutdown mode, the
current drawn by BIAS is less than 2µA. This feature is
extremely useful in an automotive application where the
BIAS input is derived from an always-on LDO expecting
to provide minimal dark current. For normal operation,
drive EN high or connect EN to IN (BIAS for MAX15028)
for continuous on operation. During shutdown, an internal 10kΩ resistor is connected between OUT and GND.
Short-Circuit/
Thermal Fault Protection
The MAX15027/MAX15028 are fully protected from a
short circuit at the output through current limiting and
thermal-overload circuitry. In the fault condition when
the output is shorted to ground, the output current is
limited to a maximum of 2A. Under these conditions,
the device quickly heats up. When the junction temperature reaches +165°C (typ), the thermal-overload circuitry turns off the output, allowing the part to cool
down. When the junction temperature cools to +150°C
(typ), the output turns back on and reestablishes regulation. Current limiting and thermal protection continue
until the fault is removed. For continuous operation, do
not exceed the absolute maximum junction-temperature rating of TJ = +150°C.
Applications Information
Programming the Output Voltage
The MAX15027/MAX15028 feature an adjustable output
voltage from 0.5V to VIN using two external resistors
connected as a voltage-divider to FB as shown in
Figure 1. The output voltage is set by the following
equation:
R1 ⎞
⎛
VOUT = VFB ⎜1 +
⎟
⎝ R2 ⎠
where typically VFB = 0.5V. Choose R2 to be 10kΩ. Or, to
optimize load-transient response for no load to full load
transients, use the resistor-divider as a minimum load
and choose R2 to be 500Ω. To simplify resistor selection:
⎛V
⎞
R1 = R2⎜ OUT − 1⎟
⎝ VFB
⎠
Soft-Start
The MAX15027/MAX15028 feature a soft-start function
that slowly ramps up the output voltage of the regulator
based on the value of the capacitor (CSS) connected
from SS to GND. Upon power-up, CSS is charged with
a 5µA (typ) current source through SS. The voltage at
SS is compared to the internal 0.5V reference (VREF).
The feedback voltage for regulation (VREG) is the lower
of VSS or VREF. As VSS rises, the regulation voltage
(VREG) rises at the same rate. Once VSS reaches and
rises above VREF, the regulation voltage then tracks the
reference voltage since it is the lower of VSS and VREF.
The value of CSS determines the length of the soft-start
time, tSS. Use the following formula to determine CSS.
CSS = 10-5 x tSS
where CSS is in farads and tSS is in seconds.

Capacitor Selection and
Regulator Stability
Capacitors are required at the MAX15027/MAX15028’s
inputs and outputs for stable operation over the full
temperature range and with load currents up to 1A.
Connect a 1µF capacitor between IN and ground and a
4.7µF capacitor with low equivalent series resistance
(ESR) between OUT and ground for 1A output current.
The input capacitor (CIN) lowers the source impedance
of the input supply. If input supply source impedance is
high, place a larger input capacitor close to IN to prevent VIN sagging due to load transients. Smaller output
capacitors can be used for output currents less than
1A. Calculate the minimum COUT as follows:
⎛ 1μF ⎞
COUT = IOUT(MAX) × ⎜
⎟
⎝ 0.25A ⎠
Operating Region and
Power Dissipation
The maximum power dissipation depends on the thermal resistance of the IC package and circuit board, the
temperature difference between the die junction and
ambient air, and the rate of airflow. The power dissipated in the device is P DISS = I OUT (V IN - V OUT). The
package features an exposed thermal pad on its
underside. This pad lowers the thermal resistance of
the package by providing a direct heat conduction
path from the die to the PCB. Connect the exposed
backside pad and GND to the system ground using a
large pad or ground plane and multiple vias to the
ground plane layer.

Regulators with BIAS Input
Noise, PSRR, and Transient Response
The MAX15027/MAX15028 are designed to operate
with low-dropout voltages and low quiescent currents
while still maintaining good noise performance, transient response, and AC rejection (see the Typical
Operating Characteristics for a plot of Power-Supply
Rejection Ratio (PSRR) vs. Frequency). When operating
from noisy sources, improved supply-noise rejection
and transient response can be achieved by increasing
the values of the input and output bypass capacitors
and through passive filtering techniques. The
MAX15027/MAX15028 load-transient response graphs
(see the Typical Operating Characteristics) show two
components of the output response: a DC shift from the
output impedance due to the load current change, and
the transient response. A typical transient overshoot for
a step change in the load current from 300mA to
800mA is 15mV. Use ceramic output capacitors greater
than 4.7µF (up to 100µF) to attenuate the overshoot.
Layout Guidelines
The TDFN package has an exposed thermal pad on its
underside. This pad provides a low thermal resistance
path for heat transfer into the PCB. This low thermally
resistive path carries a majority of the heat away from
the IC. The PCB is effectively a heatsink for the IC. The
exposed pad should be connected to a large ground
plane for proper thermal and electrical performance.
The minimum size of the ground plane is dependent
upon many system variables. To create an efficient
path, the exposed pad should be soldered to a thermal
landing, which is connected to the ground plane by
thermal vias. The thermal landing should be at least as
large as the exposed pad.
