General Description

Benefits and Features

The MAX38902A/B/C/D are low-noise, linear regulators

● 1.7V to 5.5V Input Voltage Range

that deliver up to 500mA of output current with only

● 0.6V to 5.3V Output Voltage Range

10.5µV

of output noise from 10Hz to 100kHz. These

● 10.5μV

Output Noise, 10Hz to 100kHz

RMS

regulators maintain ±1% output accuracy over a wide in-

put voltage range, requiring only 100mV of input-to-output

headroom at full load. The 365µA no-load supply current

is independent of dropout voltage.

● 365μA Operating Supply Current

● 70dB PSRR at 10kHz

● 500mA Maximum Output Current

● ±1% DC Accuracy over Load, Line, and Temperature

● 100mV (max) Dropout at 500mA Load (3.6V )

The MAX38902A have nine, pin-selectable output volt-

ages 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.

● < 0.1μA Shutdown Supply Current

● Stable with 2μF (min) Output Capacitance

● Programmable Soft-Start Rate

● Overcurrent and Overtemperature Protection

● Output-to-Input Reversed Current Protection

● POK Output

● Pin-to-Pin Compatible with MAX8902 (TDFN)

● 1.22mm x 0.82mm, 2 x 3 Bump, 0.4mm Pitch WLP; or

2mm x 2mm, 8-Pin TDFN Package

The MAX38902D have factory-preset output voltages

ranging from 0.7V to 5V. All versions include a program-

mable output soft-start rate, output overcurrent, and ther-

mal-overload protection.

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).

Ordering Information appears at end of data sheet.
