LP2980-ADJEP
Micropower SOT, 50 mA Ultra Low-Dropout Adjustable
Voltage Regulator
General Description
The LP2980-ADJEP is a 50 mA adjustable voltage regulator
designed to provide ultra low dropout in battery powered ap-
plications.
Using an optimized VIP® (vertically Integrated PNP) process,
the LP2980-ADJEP delivers unequalled performance in all
specifications critical to battery-powered designs:
Adjustable Output: output voltage can be set from 1.23V to
15V.
Precision Reference: 0.75% 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: SOT-23 package uses minimum
board space.
