The LP2980-N 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-N delivers unequaled performance in all specifications critical to battery-powered designs:
Dropout voltage: Typically 120 mV at 50-mA load, and 7mV at 1-mA load.
Ground pin current: Typically 375 μA at 50-mA load, and 80 μA at 1-mA load.
Sleep mode: Less than 1-μA quiescent current when ON/OFF pin is pulled low.
Minimum part count: Requires only a 1-μF capacitor on the regulator output.
Precision output: 0.5% tolerance output voltages available (A grade).
5-V, 4.7-V, 3.3-V, 3-V, and 2.5-V versions available as standard products.
