The LP2981-N is a 100-mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications.
Using an optimized Vertically Integrated PNP (VIP) process, the LP2981-N delivers unequaled performance in all specifications critical to battery-powered designs:
Dropout Voltage: Typically 200 mV at 100-mA load, and 7 mV at 1-mA load.
Ground Pin Current: Typically 600 μA at 100-mA load, and 80 μA at 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).
Assorted voltage options, from 2.5 V to 5 V, are available as standard products.
