The LP2982 is a 50 mA, fixed-output voltage regulator designed to provide ultra low dropout and lower noise in battery powered applications.
Using an optimized VIP (Vertically Integrated PNP) process, the LP2982 delivers unequaled performance in all specifications critical to battery-powered designs:
Dropout Voltage: Typically 120 mV @ 50 mA load, and 7mV @ 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.
Precision Output: 1.0% tolerance output voltages available (A grade).
Low Noise: By adding an external bypass capacitor, output noise can be reduced to 30 μV (typical).
Four output voltage versions, from 3.0V to 5.0V, are available as standard products.
