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 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: 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
■ Guaranteed 150 mA output current
■ Smallest possible size (micro SMD)
■ Requires minimum external components
■ Stable with low-ESR output capacitor
■ <1 µA quiescent current when shut down
■ Low ground pin current at all loads
■ Output voltage accuracy 1% (A Grade)
■ High peak current capability
■ Wide supply voltage range (16V max)
■ Low ZOUT: 0.3Ω typical (10 Hz to 1 MHz)
■ Overtemperature/overcurrent protection
■ −40°C to +125°C junction temperature range
■ Custom voltages available
Applications
■ Cellular Phone
■ Palmtop/Laptop Computer
■ Personal Digital Assistant (PDA)
■ Camcorder, Personal Stereo, Camera
