150mA, Low-Dropout Linear Regulator
with Power-OK Output
General Description
The MAX8875 low-dropout linear regulator operates from
a +2.5V to +6.5V input range and delivers up to 150mA.
A P-channel MOSFET pass transistor allows its 85µA sup-
ply current to remain independent of the load, making this
device ideal for battery-operated portable equipment
such as PCS phones, cellular phones, cordless phones,
and modems.
The MAX8875 features a power-OK output that indicates
when the output is out of regulation. The device is avail-
able in several preset output voltage versions: 5.0V, 3.3V,
3.0V, 2.7V, or 2.5V. Other features include 1µA (max) shut-
down current, short-circuit protection, thermal shutdown
protection, and reverse-battery protection. The device
comes in a miniature 5-pin SOT23 package.
The MAX8875 is optimized for use with a 1µF ceramic out-
put capacitor. For a pin-compatible, functionally equivalent
device for use with a higher ESR output capacitor, see the
MAX8885 data sheet.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
