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.
