regulators maintain ±1% output accuracy over a wide
input voltage range, requiring only 100mV of input-to-
output headroom at full load. The 365µA no-load supply
current is independent of drop-out voltage.
● 365µA Operating Supply Current
● 70dB PSRR at 10kHz
● 500mA Maximum Output Current
The MAX38902Ahave nine, pin-selectable output voltages
1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 4.0V, and 5V. The
MAX38902B/C have a resistor adjustable output voltage
in the range of 0.6V to 5.3V. The MAX38902B also
includes an active-low POK output.
● ±1% DC Accuracy Over Load, Line,
and Temperature
● 100mV (Max) Dropout at 500mA Load (3.6V )
IN
● < 0.1µA Shutdown Supply Current
● Stable with 2µF (Min) Output Capacitance
● Programmable Soft-Start Rate
The MAX38902D have factory-preset output voltages
ranging from 0.7V to 5V. All versions include a programmable
output soft-start rate, output overcurrent and thermal
overload protection.
● Overcurrent and Overtemperature Protection
● Output-to-Input Reversed Current Protection
● POK Output
The MAX38902A/B are offered in an 8-pin TDFN package,
while the MAX38902C/D are offered in a 2 x 3, 0.4mm
wafer-level package (WLP).
● Pin-to-Pin compatible with MAX8902 (TDFN)
● 1.22mm x 0.82mm, 2 x 3 Bump, 0.4mm Pitch WLP,
Applications
● Communication Circuitry
or 2mm x 2mm 8-pin TDFN Package

Protection Features
Detailed Description
The MAX38902A/B/C/D are fully protected from an output
short-circuit by a current-limiting and thermal overload
circuit. If the output is shorted to GND, the output current
is limited to 700mA (typ). Under these conditions, the part
quickly heats up. When the junction temperature reaches
165°C, a thermal limit circuit shuts off the output device.
When the junction cools to 150°C, the output turns back
on in an attempt to reestablish regulation. While the fault
persists, the output current cycles on and off, as the junc-
tion temperature slews between 150°C and 165°C.
The MAX38902A/B/C/D low noise linear regulators deliver
up to 500mAof output current with only 12µV
of output
RMS
noise in a 10Hz to100kHz bandwidth. These regulators
maintain their output voltage over a wide input range, requir-
ing only 100mV of input-to-output headroom at full load.
The MAX38902 maintains a low 365µA typical supply
current, independent of the load current and drop-out
voltage. The regulator control circuitry includes a pro-
grammable soft-start circuit, short-circuit, reverse input
current, and thermal overload protection. Other features
include an enable input and power-okay (POK) output
(MAX38902B only). See Functional Diagram.
The MAX38902A/B/C/D are also protected against reverse
current when the output voltage is higher than the input.
In the event that extra output capacitance is used at the
output, a power-down transient at the input would normally
cause a large reverse current through a conventional
regulator. The MAX38902A/B/C/D include a reverse volt-
age detector that trips when IN drops 10mV below OUT,
shutting off the regulator and opening the PMOS body
diode connection, preventing any reverse current.
Enable (EN)
The MAX38902A/MAX38902B/MAX38902C/MAX38902D
include an enable input (EN). Pull EN low to shut down
the output, or drive EN high to enable the output. If a sep-
arate shutdown signal is not available, connect EN to IN.
Bypass (BYP)
Output Voltage Configuration (MAX38902A)
The capacitor connected from BYP to OUT filters the
noise of the reference, feedback resistors and regulator
input stage, and provides a high-speed feedback path for
improved transient response. A 0.01µF capacitor rolls-off
input noise at around 32Hz.
The MAX38902A output can be set to one of nine voltages
by shorting or opening the SELA and SELB inputs, as
shown in Table 1. SELA and SELB should be connected
to GND, IN, or left unconnected. Alternatively, they may
be driven high, low, or open with external logic. However,
the states of SELA and SELB are sampled only at startup.
The regulation voltage can be set to a different level by
cycling EN or IN momentarily to GND.
The slew rate of the output voltage during startup is also
determined by the BYP capacitor. A 0.01µF capacitor sets
the slew rate to 5V/ms. This startup rate results in a 50mA
slew current drawn from the input at start-up to charge the
10µF output capacitance.
The BYP capacitor value can be adjusted from 0.001µF
to 0.1µF to change the startup slew rate according to the
following formula:

Output Voltage Configuration (MAX38902B/C)
Output Voltage Configuration (MAX38902D)
The MAX38902B and MAX38902C use external feed-
back resistors to set the output regulation voltage as
shown in Typical Operating Circuits. The output can be
set from 0.6V to 5.3V. Set the lower feedback resistor R2
to 300kΩ or less to minimize FB input bias current error.
Then calculate the value of the upper feedback resistor
R3 as follows:
The MAX38902D output voltage comes pre-programmed
to values listed below. Additionally, any voltage between
0.7V and 5.3V in 50mV steps can be factory trimmed, and
special ordered.
Power-OK (MAX38902B)
The MAX38902B includes an additional open-drain out-
put, POK, that goes low to indicate the output voltage is
in regulation. Connect a pullup resistor from this pin to an
external supply. During startup, POK stays high until the
output voltage rises to 91%(typ) of its regulation level. If
an overload occurs at the output, or the output is shut-
down, POK goes high.

A 4.7µF ceramic capacitor is recommended for the input.
Select a capacitor that maintains its capacitance over
temperature and DC bias. Capacitors with X5R or X7R
temperature characteristics generally perform well.

A minimum of 2µF capacitance is required at OUT to
ensure stability. Select a ceramic capacitor that main-
tains its capacitance (2µF minimum) over temperature
and DC bias. Capacitors with X5R or X7R temperature
characteristics generally perform well. For example, the
ceramic capacitor part number GRM155R60J475ME47
from Murata (4.7µF/6.3V/X5R ) derates to around 2.9µF
with 1.8V dc bias.

Thermal Considerations
The MAX38902A/B is packaged in an 8-pin 2mm x 2mm
TDFN package with an exposed paddle. The exposed
paddle is the main path for heat to leave the IC, and there-
fore must be connected to a ground plane with thermal
vias to allow heat to dissipate from the device. Thermal
properties of the IC package are given in the Package
Information section.
