LP2992 Micropower 250 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and

WSON Packages Designed for Use with Very Low ESR Output Capacitors

Check for Samples: LP2992

FEATURES

DESCRIPTION

The LP2992 is a 250 mA, fixed-output voltage

regulator designed to provide ultra low-dropout and

low noise in battery powered applications.

•

Ultra Low Dropout Voltage

•

Specified 250 mA Output Current

Smallest Possible Size (SOT-23, WSON

Package)

Using an optimized VIP (Vertically Integrated PNP)

process, the LP2992 delivers unequaled performance

in all specifications critical to battery-powered

designs:

•

Requires Minimum External Components

Stable with Low-ESR Output Capacitor

<1 µA Quiescent Current when Shut Down

Low Ground Pin Current at all Loads

Output Voltage Accuracy 1% (A Grade)

High Peak Current Capability

Dropout Voltage: Typically 450 mV @ 250 mA load,

and 5 mV @ 1 mA load.

Ground Pin Current: Typically 1500 µA @ 250 mA

load, and 75 µA @ 1 mA load.

Wide Supply Voltage Range (16V Max)

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

Overtemperature/overcurrent Protection

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

Custom Voltages Available

Enhanced Stability: The LP2992 is stable with

output capacitor 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 WSON

packages use 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

Low Noise: By adding a 10 nF bypass capacitor,

output noise can be reduced to 30 µV (typical).

Multiple voltage options, from 1.5V to 5.0V, are

available as standard products. Consult factory for

custom voltages.
