LP2985

Micropower 150 mA Low-Noise Ultra Low-Dropout

Regulator in SOT-23 and micro SMD Packages

Designed for Use with Very Low ESR Output Capacitors

General Description

Features

n Ultra low dropout voltage

The LP2985 is a 150 mA, fixed-output voltage regulator

designed to provide ultra low-dropout and low noise in bat-

tery powered applications.

n Guaranteed 150 mA output current

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

n Requires minimum external components

n Stable with low-ESR output capacitor

™

Using an optimized VIP (Vertically Integrated PNP) pro-

cess, the LP2985 delivers unequalled performance in all

specifications critical to battery-powered designs:

1 µA quiescent current when shut down

Dropout Voltage: Typically 300 mV

150 mA load, and

n Low ground pin current at all loads

n Output voltage accuracy 1% (A Grade)

n High peak current capability

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

n Custom voltages available

7 mV 1 mA load.

Ground Pin Current: Typically 850 µA 150 mA load, and

75 µA 1 mA load.

Enhanced Stability: The LP2985 is stable with output ca-

pacitor ESR as low as 5 mΩ, which allows the use of ceramic

capacitors on the output.

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.

Applications

n Cellular Phone

Precision Output: 1% tolerance output voltages available

(A grade).

n Palmtop/Laptop Computer

n Personal Digital Assistant (PDA)

n Camcorder, Personal Stereo, Camera

Low Noise: By adding a 10 nF bypass capacitor, output

noise can be reduced to 30 µV (typical).

Multiple voltage options, from 2.5V to 5.0V, are available as

standard products. Consult factory for custom voltages.
