Micropower 150 mA Low-Noise Low-Dropout Regulator in
SOT-23 and micro SMD packages for Applications with
Output Voltages ⤠2.0V
Designed for Use with Very Low ESR Output Capacitors
General Description
The LP2985LV is a 150 mA, fixed-output voltage regulator
designed to providehigh performance and low noise in appli-
cations requiring output voltages ⤠2.0V.
Using an optimized VIP® (Vertically Integrated PNP) process,
the LP2985LV delivers unequalled performance in all speci-
fications critical to battery-powered designs:
Ground Pin Current: Typically 825 µA @ 150 mA load, and
75 µA @ 1 mA load.
Enhanced Stability: The LP2985LV is stable with output ca-
pacitor ESR as low as 5 mâ¦, 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: micro SMD package uses 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).
