LP2981 Micropower 100 mA Ultra Low-Dropout
Regulator
General Description
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) process, 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-23and micro S...
