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 mAload, 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.
