SOT-23 and micro SMD Packages
General Description
The LP2980 is a 50 m A, fixed-output voltage regulator designed specifically to meet the requirements of batterypowered applications.
Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2980 delivers unequaled performance in all specifications critical to battery-powered designs:
Dropout Voltage. Typically 120 m V @ 50 m A load, and 7 m V @ 1 m A load.
Ground Pin Current. Typically 375 µA @ 50 m A load, and 80 µA @ 1 m A load.
Sleep Mode. Less than 1 µA quiescent current when ON/ OFF pin is pulled low.
Smallest Possible Size. SOT-23 and micro SMD packages use an absolute minimum board space.
Minimum Part Count. Requires only 1 µF of external capacitance on the regulator output.
Precision Output. 0.5% tolerance output voltages available (A grade).
