LP2985  
Micropower 150 mA Low-Noise Ultra Low-Dropout  
Regulator in SOT-23 and micro SMD Packages  
Designed for Use with Very Low ESR Output Capacitors  
General Description  
Features  
n Ultra low dropout voltage  
The LP2985 is a 150 mA, fixed-output voltage regulator  
designed to provide ultra low-dropout and low noise in bat-  
tery powered applications.  
n Guaranteed 150 mA output current  
n Smallest possible size (SOT-23, micro SMD package)  
n Requires minimum external components  
n Stable with low-ESR output capacitor  
™
Using an optimized VIP (Vertically Integrated PNP) pro-  
cess, the LP2985 delivers unequalled performance in all  
specifications critical to battery-powered designs:  
<
n
1 µA quiescent current when shut down  
@
Dropout Voltage: Typically 300 mV  
150 mA load, and  
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: 0.3Ω typical (10 Hz to 1 MHz)  
n Overtemperature/overcurrent protection  
n −40˚C to +125˚C junction temperature range  
n Custom voltages available  
@
7 mV 1 mA load.  
@
Ground Pin Current: Typically 850 µA 150 mA load, and  
@
75 µA 1 mA load.  
Enhanced Stability: The LP2985 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: SOT-23 and micro SMD packages  
use absolute minimum board space.  
Applications  
n Cellular Phone  
Precision Output: 1% tolerance output voltages available  
(A grade).  
n Palmtop/Laptop Computer  
n Personal Digital Assistant (PDA)  
n Camcorder, Personal Stereo, Camera  
Low Noise: By adding a 10 nF bypass capacitor, output  
noise can be reduced to 30 µV (typical).  
Multiple voltage options, from 2.5V to 5.0V, are available as  
standard products. Consult factory for custom voltages.
