LP2981

Micropower 100 mA Ultra Low-Dropout Regulator

General Description

The LP2981 is a 100 mA, fixed-output voltage regulator de-

signed specifically to meet the requirements of

battery-powered applications.

Features

n Ultra low dropout voltage

n Output voltage accuracy 0.75% (A Grade)

n Guaranteed 100 mA output current

™

Using an optimized VIP (Vertically Integrated PNP) pro-

n Smallest possible size (SOT-23, micro SMD package)

cess, the LP2981 delivers unequaled performance in all

specifications critical to battery-powered designs:

1 µA quiescent current when shutdown

n Low ground pin current at all load currents

n High peak current capability (300 mA typical)

n Wide supply voltage range (16V max)

n Fast dynamic response to line and load

n Low Z_OUTover wide frequency range

n Overtemperature/overcurrent protection

n −40˚C to +125˚C junction temperature range

Dropout Voltage. Typically 200 mV

100 mA load, and

7 mV 1 mA load.

Ground Pin Current. Typically 600 µA 100 mA load, and

80 µA 1 mA load.

Sleep Mode. Less than 1 µA quiescent current when ON/

OFF pin is pulled low.

Smallest Possible Size. SOT-23and micro SMD packages

use an absolute minimum board space.

Applications

Precision Output. 0.75% tolerance output voltages avail-

able (A grade).

n Cellular Phone

n Palmtop/Laptop Computer

n Personal Digital Assistant (PDA)

n Camcorder, Personal Stereo, Camera

Eleven voltage options, from 2.5V to 5.0V, are available as

standard products.
