DescriptionThe LP2985LV-Nisa 150-mA, fixed-output voltage
regulator designedto provide high performance and
low noisein applications requiring output voltages≤2
Using an optimized vertically integrated PNP (VIP)
process, the LP2985LV-N delivers unequaled
performancein all specifications critical to battery-
powered designs: Ground Pin Current: Typically 825 µAat 150-mA
load, and75 µAat 1-mA load. Enhanced Stability: The LP2985LV-Nis 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. Precision Output: 1% tolerance output voltages
available(A grade). Low Noise: By addinga 10-nF bypass capacitor,
output noise canbe reducedto30 µV (typical).
