LP2981 Micropower 100 mA Ultra Low-Dropout Regulator
March 2000
LP2981
Micropower 100 mA Ultra Low-Dropout Regulator
General Description
The LP2981 is a 100 mA, fixed-output voltage regulator de-
signed specifically to meet the requirements of
battery-powered applications.
Using an optimized VIP
鈩?/div>
(Vertically Integrated PNP) pro-
cess, the LP2981 delivers unequaled performance in all
specifications critical to battery-powered designs:
Dropout Voltage.
Typically 200 mV
@
100 mA load, and
7 mV
@
1 mA load.
Ground Pin Current.
Typically 600 碌A(chǔ)
@
100 mA load, and
80 碌A(chǔ)
@
1 mA load.
Sleep Mode.
Less than 1 碌A(chǔ) quiescent current when ON/
OFF pin is pulled low.
Smallest Possible Size.
SOT-23and micro SMD packages
use an absolute minimum board space.
Precision Output.
0.75% tolerance output voltages avail-
able (A grade).
Eleven voltage options, from 2.5V to 5.0V, are available as
standard products.
