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 output voltages below 2V. Using an optimized VIP™ (Vertically Integrated PNP) process, 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
