LP2982
Micropower 50 mA Ultra Low-Dropout Regulator
General Description
The LP2982 is a 50 mA, fixed-output voltage regulator de-
signed to provide ultra low dropout and lower noise in battery
powered applications.
Using an optimized VIP™ (Vertically Integrated PNP) pro-
cess, the LP2982 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 absolute minimum board space.
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).
Ten output voltage versions, from 2.5V to 5.0V, are available
as standard products.
