3 Description
The LP2982 is a 50-mA, 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 mV at 50 mA load,
and 7 mV 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.
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).
