LP2980-ADJ Micropower SOT, 50 mA Ultra Low-Dropout Adjustable Voltage Regulator

April 2000

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.

Using an optimized VIP

鈩?/div>

(vertically Integrated PNP) pro-

cess, the LP2980-ADJ delivers unequalled performance in

all specifications critical to battery-powered designs:

Adjustable Output:

output voltage can be set from 1.23V to

15V.

Precision Reference:

0.75% tolerance.

Dropout Voltage:

typically 120 mV

50 mA load, and 7 mV

1 mA load.

Ground Pin Current:

typically 320 碌A(chǔ)

50 mA load, and 80

碌A(chǔ)

1 mA load.

Sleep Mode:

less than 1 碌A(chǔ) quiescent current when on/off

pin is pulled low.

Smallest Possible Size:

SOT-23 package uses minimum

board space.

Features

Ultra low dropout voltage

Output adjusts from 1.23V to 15V

Guaranteed 50 mA output current

Uses tiny SOT-23 package

Requires few external components

1 碌A(chǔ) quiescent current when shutdown

Low ground pin current at all loads

High peak current capability (150 mA typical)

Wide supply voltage range (2.5V鈥?6V)

Overtemperature/overcurrent protection

鈭?0藲C to +125藲C Junction temperature range

Applications

Cellular Phone

Palmtop/Laptop Computer

Camcorder, Personal Stereo, Camera
