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.
