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 (A grade).
Features
n n n n n n n n n n n n Guaranteed 50 mA output current Smallest possible size (SOT-23 Package) Requires few external components < 1 µA quiescent current when shutdown Low ground pin current at all load currents Output
voltage accuracy 0.5% (A Grade) High peak current capability (150 mA typical) Wide supply
