The LP2980-ADJ is a 50 mA adjustable voltage regulator designed to provide ultra low dropout in battery powered applications.

Using an optimized VIP (vertically Integrated PNP) process, the LP2980-ADJ delivers unequaled performance in all specifications critical to battery-powered designs:

Adjustable Output: output voltage can be set from 1.23V to 15V.

Precision Reference: 1.0% tolerance.

Dropout Voltage: typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load.

Ground Pin Current: typically 320 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.

Smallest Possible Size: Package uses minimum board space.
