LP2981 Micropower 100 mA Ultra Low-Dropout Regulator

The LP2981 is a 100 mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications. Using an optimized VIP™ (Vertically Integrated PNP) pro- cess, the LP2981 delivers unequaled performance in all specifications critical to battery-powered designs: Dropout Voltage. Typically 200 mV @ 100 mA load, and 7 mV @ 1 mA load. Ground Pin Current. Typically 600 µA @ 100 mA load, and 80 µA @ 1 mA 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. Precision Output. 0.75% tolerance output voltages avail- able (A grade). Eleven voltage options, from 2.5V to 5.0V, are available as standard products.
