LP2980-ADJ

Micropower SOT, 50 mA Ultra Low-Dropout Adjustable

Voltage Regulator

General Description

The LP2980-ADJ is a 50 mA adjustable voltage regulator de-

signed to provide ultra low dropout in battery powered appli-

cations.

Features

n Ultra low dropout voltage

n Output adjusts from 1.23V to 15V

n Guaranteed 50 mA output current

n Uses tiny SOT-23 package

n Requires few external components

™

Using an optimized VIP (vertically Integrated PNP) pro-

cess, the LP2980-ADJ delivers unequalled performance in

all specifications critical to battery-powered designs:

1 µA quiescent current when shutdown

Adjustable Output: output voltage can be set from 1.23V to

n Low ground pin current at all loads

15V.

n High peak current capability (150 mA typical)

n Wide supply voltage range (2.5V–16V)

n Overtemperature/overcurrent protection

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

Precision Reference: 0.75% tolerance.

Dropout Voltage: typically 120 mV 50 mA load, and 7 mV

1 mA load.

Ground Pin Current: typically 320 µA 50 mA load, and 80

µA 1 mA load.

Applications

Sleep Mode: less than 1 µA quiescent current when on/off

pin is pulled low.

n Cellular Phone

n Palmtop/Laptop Computer

n Camcorder, Personal Stereo, Camera

Smallest Possible Size: SOT-23 package uses minimum

board space.
