LP2980
Micropower 50 mA Ultra Low-Dropout Regulator In
SOT-23 and micro SMD Packages
General Description
The LP2980 is a 50 mA, fixed-output voltage regulator de-
signed specifically to meet the requirements of battery-
powered applications.
Using an optimized VIP(Vertically Integrated PNP) pro-
cess, the LP2980 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 an absolute minimum board space.
Minimum Part Count. Requires only 1 µF of external ca-
pacitance on the regulator output.
Precision Output. 0.5% tolerance output voltages available
(A grade).
5.0V, 3.3V, and 3.0V versions available as standard prod-
ucts.
