LP2981-N Micropower 100 mA Ultra Low-Dropout Regulator in SOT-23 Package

Check for Samples: LP2981-N

FEATURES

DESCRIPTION

The LP2981-N is a 100 mA, fixed-output voltage

regulator designed specifically to meet the

requirements of battery-powered applications.

•

Ultra Low Dropout Voltage

•

Output Voltage Accuracy 0.75% (A Grade)

Specified 100 mA Output Current

Using an optimized VIP (Vertically Integrated PNP)

< 1 μA Quiescent Current when Shutdown

Low Ground Pin Current at All Load Currents

High Peak Current Capability (300 mA Typical)

Wide Supply Voltage Range (16V Max)

Fast Dynamic Response to Line and Load

Low Z_OUTOver Wide Frequency Range

Overtemperature/Overcurrent Protection

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

process,

the

LP2981-N

delivers

unequaled

performance in all specifications critical to battery-

powered designs:

Dropout Voltage. Typically 200 mV @ 100 mA load,

and 7 mV @ 1 mA load.

Ground Pin Current. Typically 600 μA @ 100 mA

load, and 80 μA @ 1 mA load.

Sleep Mode. Less than 1 μA quiescent current when

ON/OFF pin is pulled low.

APPLICATIONS

Precision Output. 0.75% tolerance output voltages

available (A grade).

•

Cellular Phone

Nine voltage options, from 2.5V to 5.0V, are available

as standard products.

Palmtop/Laptop Computer

Personal Digital Assistant (PDA)

Camcorder, Personal Stereo, Camera
