12μVRMS Low Noise 500mA
LDO Linear Regulator
General Description
The MAX38902A/B/C/D are low-noise, linear regulators
that deliver up to 500mA of output current with only
12µVRMS of output noise from 10Hz to 100kHz. These
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.
The MAX38902A have 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.
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.
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).

For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
