DESCRIPTION
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.
