DescriptionThe LP2992 isa 250-mA, fixed-output voltage
regulator designedto provide ultra-low dropout and
low noisein battery-powered applications.
Using an optimized vertically integrated PNP (VIP)
process, the LP2992 delivers unequaled performance all specifications critical to battery-powered
designs: Dropout voltage: Typically 450 mV at 250-mA
load, and5 mVat 1-mA load. Ground pin current: Typically 1500 µAat 250-mA
load, and75 µAat 1-mA load. Enhanced stability: The LP2992is stable with
output capacitor equivalent series resistance
(ESR) as low as5 mΩ, which allows the useof
ceramic capacitorson the output. Sleep mode: Less than 1-µA quiescent current
when ON/OFF pinis 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 addinga 10-nF bypass capacitor,
output noise canbe reducedto30 µV (typical). Multiple voltage options, from 1.5Vto5V, are
availableas standard products. Consult factory for
custom voltages.
