LP2985LV
Micropower 150 mA Low-Noise Low-Dropout Regulator
in SOT-23 and micro SMD packages for Applications
with Output Voltages 2.3V
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 ap-
plications requiring output voltages < 2.3V.
Using an optimized VIP(Vertically Integrated PNP) pro-
cess, the LP2985LV delivers unequalled performance in all
specifications 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
capacitor 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: 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).
Features
n Guaranteed 150 mA output current
n Smallest possible size (micro SMD)
n Requires minimum external components
n Stable with low-ESR output capacitor
n <1 µA quiescent current when shut down
n Low ground pin current at all loads
n Output voltage accuracy 1% (A Grade)
n High peak current capability
n Wide supply voltage range (16V max)
n Low ZOUT: 0.3typical (10 Hz to 1 MHz)
n Overtemperature/overcurrent protection
n −40˚C to +125˚C junction temperature range
n Custom voltages available
Applications
n Cellular Phone
n Palmtop/Laptop Computer
n Personal Digital Assistant (PDA)
n Camcorder, Personal Stereo, Camera

Basic Application Circuit
10129502
*ON/OFF input must be actively terminated. Tie to VIN if this function is not to be used.
**Minimum capacitance is shown to ensure stability (may be increased without limit). Ceramic capacitor required for output (see Application Hints).
***Reduces output noise (may be omitted if application is not noise critical). Use ceramic or film type with very low leakage current (see Application Hints).
