LP2982

Micropower 50 mA Ultra Low-Dropout Regulator

General Description

The LP2982 is a 50 mA, fixed-output voltage regulator de-

signed to provide ultra low dropout and lower noise in battery

powered applications.

Features

n Ultra low dropout voltage

n Guaranteed 50 mA output current

n Typical dropout voltage 180 mV 80 mA

™

Using an optimized VIP (Vertically Integrated PNP) pro-

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

n Requires minimum external components

cess, the LP2982 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 loads

1 mA load.

n Output voltage accuracy 1.0% (A Grade)

n High peak current capability (150 mA typical)

n Wide supply voltage range (16V max)

n Low Z_OUT0.3Ω typical (10 Hz to 1 MHz)

n Overtemperature/overcurrent protection

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

n Custom voltages available

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 absolute minimum board space.

Precision Output: 1.0% tolerance output voltages available

(A grade).

Applications

Low Noise: By adding an external bypass capacitor, output

noise can be reduced to 30 µV (typical).

n Cellular Phone

n Palmtop/Laptop Computer

n Personal Digital Assistant (PDA)

n Camcorder, Personal Stereo, Camera

Ten output voltage versions, from 2.5V to 5.0V, are available

as standard products.
