General Description

The LP2980 is a 50 mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications

Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2980 delivers unequaled performance in all specifications critical to battery-powered designs:

Dropout Voltage. Typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load.

Ground Pin Current. Typically 375 µA @ 50 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. Minimum Part Count. Requires only 1 µF of external capacitance on the regulator output.

Precision Output. 0.5% tolerance output voltages available (A grade). 5.0V, 3.3V, and 3.0V versions available as standard products
