LP2980

Micropower 50 mA Ultra Low-Dropout Regulator

General Description

The LP2980 is a 50 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 0.5% (A Grade)

n Guaranteed 50 mA output current

™

Using an optimized VIP (Vertically Integrated PNP) pro-

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

n Requires only 1 µF external capacitance

cess, the LP2980 delivers unequaled performance in all

specifications critical to battery-powered designs:

1 µA quiescent current when shutdown

Dropout Voltage. Typically 120 mV 50 mA load, and 7 mV

n Low ground pin current at all load currents

n High peak current capability (150 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

1 mA load.

Ground Pin Current. Typically 375 µA 50 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-23 and micro SMD packages

use an absolute minimum board space.

Minimum Part Count. Requires only 1 µF of external ca-

pacitance on the regulator output.

Applications

n Cellular Phone

Precision Output. 0.5% tolerance output voltages available

(A grade).

n Palmtop/Laptop Computer

n Personal Digital Assistant (PDA)

n Camcorder, Personal Stereo, Camera

5.0V, 3.3V, and 3.0V versions available as standard prod-

ucts.
