LP2980-ADJ
Micropower SOT, 50 mA Ultra Low-Dropout Adjustable
Voltage Regulator
General Description
The LP2980-ADJ is a 50 mA adjustable voltage regulator de-
signed to provide ultra low dropout in battery powered appli-
cations.
Using an optimized VIP(vertically Integrated PNP) pro-
cess, the LP2980-ADJ 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.
Features
n Ultra low dropout voltage
n Output adjusts from 1.23V to 15V
n Guaranteed 50 mA output current
n Uses tiny SOT-23 package
n Requires few external components

n High peak current capability (150 mA typical)
n Wide supply voltage range (2.5V–16V)
n Overtemperature/overcurrent protection
n −40˚C to +125˚C Junction temperature range
Applications
n Cellular Phone
n Palmtop/Laptop Computer
n Camcorder, Personal Stereo, Camera
