LP2980LV
Micropower SOT, 50 mA Low-Voltage Low-Dropout
Regulator For Applications With Output Voltages < 2V
General Description
The LP2980LV is a 50 mA, fixed-output voltage regulator de-
signed for high performance in applications requiring output
voltages below 2V.
Using an optimized VIP™ (Vertically Integrated PNP) pro-
cess, the LP2980LV delivers unequalled performance in all
specifications critical to battery-powered designs:
Low Ground Pin Current. Typically 280 µA @ 50 mA load,
and 75 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 absolute
minimum board space.
Precision Output. 0.5% tolerance output voltages available
(A grade).
Features
n Guaranteed 50 mA output current
n Smallest possible size (SOT-23 Package)
n Requires few external components
n < 1 µA quiescent current when shutdown
n Low ground pin current at all load currents
n Output voltage accuracy 0.5% (A Grade)
n High peak current capability (150 mA typical)
n Wide supply voltage range (16V max)
n Fast dynamic response to line and load
n Low ZOUT 0.1Ω typical (10 Hz to 1 MHz)
n Overtemperature/overcurrent protection
n −40˚C to +125˚C junction temperature range
Applications
n Cellular Phone
n Palmtop/Laptop Computer
n Personal Digital Assistant (PDA)
n Camcorder, Personal Stereo, Camera
