SNOS733M –APRIL 2000–REVISED JUNE 2013

LP2980-N Micropower 50 mA Ultra Low-Dropout Regulator In SOT-23 Package

Check for Samples: LP2980-N

FEATURES

DESCRIPTION

The LP2980-N is a 50 mA, fixed-output voltage

regulator designed specifically to meet the

requirements of battery-powered applications.

•

Ultra Low Dropout Voltage

•

Output Voltage Accuracy 0.5% (A Grade)

Ensured 50 mA Output Current

Using an optimized VIP (Vertically Integrated PNP)

Requires Only 1 μF External Capacitance

< 1 μA Quiescent Current When Shutdown

Low Ground Pin Current at all Load Currents

High Peak Current Capability (150 mA Typical)

Wide Supply Voltage Range (16V Max)

Fast Dynamic Response to Line and Load

Low Z_OUTOver Wide Frequency Range

process,

the

LP2980-N

delivers

unequaled

performance in all specifications critical to battery-

powered designs:

Dropout Voltage. Typically 120 mV @ 50 mA load,

and 7 mV @ 1 mA load.

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.

Over-Temperature and Over-Current

Protection

Minimum Part Count. Requires only 1 μF of external

•

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

capacitance on the regulator output.

APPLICATIONS

Precision Output. 0.5% tolerance output voltages

available (A grade).
