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  
The LP2985 is a 150 mA, fixed-output voltage regulator de-  
signed to provide ultra low-dropout and low noise in battery  
powered applications.  
Ultra low dropout voltage  
■
■
■
■
■
■
■
■
Guaranteed 150 mA output current  
Smallest possible size (SOT-23, micro SMD package)  
Using an optimized VIP® (Vertically Integrated PNP) process,  
the LP2985 delivers unequalled performance in all specifica-  
tions critical to battery-powered designs:  
Requires minimum external components  
Stable with low-ESR output capacitor  
<1 µA quiescent current when shut down  
Dropout Voltage: Typically 300 mV @ 150 mA load, and  
7 mV @ 1 mA load.  
Low ground pin current at all loads  
Output voltage accuracy 1% (A Grade)  
Ground Pin Current: Typically 850 µA @ 150 mA load, and  
75 µA @ 1 mA load.  
High peak current capability  
■
■
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.  
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  
■
■
■
■
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  
Precision Output: 1% tolerance output voltages available (A  
grade).  
Cellular Phone  
■
■
■
Low Noise: By adding a 10 nF bypass capacitor, output noise  
can be reduced to 30 µV (typical).  
Palmtop/Laptop Computer  
Personal Digital Assistant (PDA)  
Multiple voltage options, from 2.5V to 5.0V, are available as  
standard products. Consult factory for custom voltages.  
Camcorder, Personal Stereo, Camera
