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 (POK) output that indi-

cates when the output is out of regulation. The device is

available in several preset output voltage versions: 5.0V,

3.3V, 3.0V, 2.7V, 2.5V, or 1.5V. Other features include 1µA

(max) shutdown 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.
