DESCRIPTION
The LP2992 is a 250 mA, fixed-output voltage
regulator designed to provide ultra low-dropout and
low noise in battery powered applications.
Using an optimized VIP (Vertically Integrated PNP)
process, the LP2992 delivers unequaled 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 capacitor ESR as low as 5 mΩ, 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 WSON
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.
