3 Description
The LP2982 is a 50-m A, fixed-output voltage LDO designed to provide ultra-low dropout and lower noise in battery-powered applications.
Using an optimized vertically integrated PNP (VIP) process, the LP2982 delivers unequaled performance in all specifications critical to battery-powered designs:
Dropout Voltage: Typically 120 m V at 50 m A load, and 7 m V at 1 m A load.
Ground Pin Current: Typically 375 μA at 50 m A load, and 80 μA at 1 m A load.
Sleep Mode: Less than 1-μA quiescent current when ON/OFF pin is pulled low.
Precision Output: 1% tolerance output voltages available (A grade).
Low Noise: By adding an external bypass capacitor, output noise can be reduced to 30 μV (typical).
