LP2983

Micropower 150 mA Voltage Regulator in SOT-23

Package For Output Voltages ≤ 1.2V

Designed for Use with Very Low ESR Output Capacitors

General Description

The LP2983 is a 150 mA, fixed-output voltage regulator

designed to provide tight voltage regulation in applications

with output voltages ≤ 1.2V.

Features

n Guaranteed 150 mA output current

n Smallest possible size (SOT-23 package)

n Requires minimum external components

n Stable with low-ESR output capacitor

n Low ground pin current at all loads

n Output voltage accuracy 1% (A Grade)

n High peak current capability

™

Using an optimized VIP (Vertically Integrated PNP) pro-

cess, the LP2983 delivers unequalled performance in all

critical specifications:

Ground Pin Current: Typically 825 µA 150 mA load, and

75 µA 1 mA load.

n Wide supply voltage range (16V max)

n Low Z_OUT: 0.3Ω typical (10 Hz to 1 MHz)

n Overtemperature/overcurrent protection

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

Enhanced Stability: The LP2983 is stable with output ca-

pacitor ESR down to zero, which allows the use of ceramic

capacitors on the output.

Smallest Possible Size: SOT-23 package uses absolute

minimum board space.

Applications

Precision Output: 1% tolerance output voltages available

(A grade).

n Cellular Phone

n Palmtop/Laptop Computer

n Personal Digital Assistant (PDA)

n Camcorder, Personal Stereo, Camera
