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).
