FEATURES

DESCRIPTION

The LP2983 is a 150 mA, fixed-output voltage

23

•

Guaranteed 150 mA Output Current

regulator designed to provide tight voltage regulation

•

Smallest Possible Size (SOT-23 Package)

in applications with output voltages

≤ 1.2V.

•

Requires Minimum External Components

Using an optimized VIP™ (Vertically Integrated PNP)

•

Stable with Low-ESR Output Capacitor

process, the LP2983 delivers unequaled performance

•

Low Ground Pin Current at All Loads

in all critical specifications:

•

Output Voltage Accuracy 1% (A Grade)

Ground Pin Current: Typically 825 µA @ 150 mA

load, and 75 µA @ 1 mA load.

•

High Peak Current Capability

•

Wide Supply Voltage Range (16V Max)

Enhanced Stability: The LP2983 is stable with

output capacitor ESR down to zero, which allows the

•

use of ceramic capacitors on the output.

•

Overtemperature/Overcurrent Protection

Smallest Possible Size: SOT-23 package uses

•

−40°C to +125°C Junction Temperature Range

absolute minimum board space.

APPLICATIONS

Precision Output: 1% tolerance output voltages

available (A grade).

•

Cellular Phone

•

Palmtop/Laptop Computer

•

Personal Digital Assistant (PDA)

•

Camcorder, Personal Stereo, Camera
