LP2992
Micropower 250 mA Low-Noise Ultra Low-Dropout
Regulator in SOT-23 and LLP Packages
Designed for Use with Very Low ESR Output Capacitors
General Description
The LP2992 is a 250 mA, fixed-output voltage regulator
designed to provide ultra low-dropout and low noise in bat-
tery powered applications.
Using an optimized VIP(Vertically Integrated PNP) pro-
cess, the LP2992 delivers unequalled performance in all
specifications critical to battery-powered designs:
Dropout Voltage: Typically 450 mV @ 250 mA load, and
5 mV @ 1 mA load.
Ground Pin Current: Typically 1500 µA @ 250 mA load, and
75 µA @ 1 mA load.
Enhanced Stability: The LP2992 is stable with output ca-
pacitor ESR as low as 5 m, which allows the use of ceramic
capacitors on the output.
Sleep Mode: Less than 1 µA quiescent current when
ON/OFF pin is pulled low.
Smallest Possible Size: SOT-23 and LLP packages use
absolute minimum board space.
Precision Output: 1% tolerance output voltages available
(A grade).
Low Noise: By adding a 10 nF bypass capacitor, output
noise can be reduced to 30 µV (typical).
Multiple voltage options, from 1.5V to 5.0V, are available as
standard products. Consult factory for custom voltages.
