LP2983

SNVS170D –OCTOBER 2001–REVISED APRIL 2016

LP2983 Micropower 150-mA Voltage Regulator in SOT-23 Package

for Output Voltages ≤ 1.2 VDesigned for Use With Very Low-ESR Output Capacitors

1 Features

3 Description

The LP2983 is

regulator designed to provide tight voltage regulation

in applications with output voltages ≤ 1.2 V.

a 150-mA, fixed-output voltage

•

Operating Input Supply Voltage: 2.2 V to 16 V

Output Current: 150 mA

•

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

Stable with Low-ESR Output Capacitor

Low Ground Pin Current at All Loads

Output Voltage Accuracy 1% (A Grade)

High Peak Current Capability

Using an optimized vertically integrated PNP (VIP)

process, the LP2983 delivers unequaled performance

in all critical specifications:

•

Ground pin current: Typically 825 µA at a 150-mA

load, and 75 µA at a 1-mA load.

•

Enhanced stability: The LP2983 is stable with

output capacitor ESR down to zero, which allows

the use of ceramic capacitors on the output.

Wide Supply Voltage Range (16 V Maximum)

Overtemperature and Overcurrent Protection

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

Requires Minimum External Components

•

Precision output: 1% tolerance output voltages

available (A grade).

Smallest possible size: SOT-23 package uses

absolute minimum board space.

2 Applications

•

Cellular Phones

Device Information⁽¹⁾

Palmtop/Laptop Computers

Personal Digital Assistants (PDA)

Camcorders, Personal Stereos, Cameras
