LP2980LV

Micropower SOT, 50 mA Low-Voltage Low-Dropout

Regulator For Applications With Output Voltages 2V

General Description

Features

n Guaranteed 50 mA output current

n Smallest possible size (SOT-23 Package)

n Requires few external components

The LP2980LV is a 50 mA, fixed-output voltage regulator

designed for high performance in applications requiring out-

put voltages below 2V.

™

1 µA quiescent current when shutdown

Using an optimized VIP (Vertically Integrated PNP) pro-

cess, the LP2980LV delivers unequalled performance in all

specifications critical to battery-powered designs:

n Low ground pin current at all load currents

n Output voltage accuracy 0.5% (A Grade)

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_OUT0.1Ω typical (10 Hz to 1 MHz)

n Overtemperature/overcurrent protection

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

Low Ground Pin Current. Typically 280 µA 50 mA load,

and 75 µA 1 mA load.

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

OFF pin is pulled low.

Smallest Possible Size. SOT-23 package uses absolute

minimum board space.

Precision Output. 0.5% tolerance output voltages available

(A grade).

Applications

n Cellular Phone

n Palmtop/Laptop Computer

n Personal Digital Assistant (PDA)

n Camcorder, Personal Stereo, Camera
