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
designed for high performance in applications requiring out-
put 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
