LP2981AIM5-2.5/NOPB

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.
