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  
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  
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:  
<
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  
@
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.  
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  
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.  
Applications  
Precision Output: 1% tolerance output voltages available  
(A grade).  
n Cellular Phone  
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).
