LP2989

Micropower/Low Noise, 500 mA Ultra Low-Dropout

Regulator

For Use with Ceramic Output Capacitors

General Description

Features

n Ultra low dropout voltage

The LP2989 is a fixed-output 500 mA precision LDO regu-

lator designed for use with ceramic output capacitors.

n Guaranteed 500 mA continuous output current

n Very low output noise with external capacitor

n SO-8, Mini SO-8, 8 Lead LLP surface mount packages

Output noise can be reduced to 18µV (typical) by connecting

an external 10 nF capacitor to the bypass pin.

0.8 µA quiescent current when shutdown

™

Using an optimized VIP (Vertically Integrated PNP) pro-

cess, the LP2989 delivers superior performance:

n Low ground pin current at all loads

n 0.75% output voltage accuracy (“A” grade)

n High peak current capability (800 mA typical)

n Wide supply voltage range (16V max)

n Overtemperature/overcurrent protection

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

Dropout Voltage: Typically 310 mV 500 mA load, and 1

mV 100 µA load.

Ground Pin Current: Typically 3 mA 500 mA load, and

110 µA 100 µA load.

Sleep Mode: The LP2989 draws less than 0.8 µA quiescent

current when shutdown pin is pulled low.

Applications

Error Flag: The built-in error flag goes low when the output

drops approximately 5% below nominal.

n Notebook/Desktop PC

n PDA/Palmtop Computer

n Wireless Communication Terminals

n SMPS Post-Regulator

Precision Output: Guaranteed output voltage accuracy is

0.75% (“A” grade) and 1.25% (standard grade) at room

temperature.

For output voltages 2V, see LP2989LV datasheet.
