LP2981 Datasheet | National Semiconductor

Description The LP2981 is a 100 m A, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications. Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2981 delivers unequaled performance in all specifications critical to battery-powered designs: Dropout Voltage. Typically 200 m V @ 100 m A load, and 7 m V @ 1 m A load. Ground Pin Current. Typically 600 µA @ 100 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-23and micro SMD packages use an absolute minimum board space. Precision Output. 0.75% tolerance output voltages available (A grade). Eleven voltage options, from 2.5V to 5.0V, are available as standard products.
