概要

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.

Precision Output. 0.75% tolerance output voltages available (A grade).

Nine voltage options, from 2.5V to 5.0V, are available as standard products.
