FEATURES  
DESCRIPTION  
The LP2985LV-N is a 150 mA, fixed-output voltage  
regulator designed to provide high performance and  
low noise in applications requiring output voltages  
2.0V.  
2
Ensured 150 mA Output Current  
Smallest Possible Size (DSBGA)  
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  
Using an optimized VIP (Vertically Integrated PNP)  
process, the LP2985LV-N delivers unequaled  
performance in all specifications critical to battery-  
powered designs:  
Ground Pin Current: Typically 825 µA @ 150 mA  
load, and 75 µA @ 1 mA load.  
Wide Supply Voltage Range (16V Max)  
Low ZOUT: 0.3Typical (10 Hz to 1 MHz)  
Overtemperature/Overcurrent Protection  
40°C to +125°C Junction Temperature Range  
Custom Voltages Available  
Enhanced Stability: The LP2985LV-N 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: DSBGA package uses  
absolute minimum board space.  
APPLICATIONS  
Cellular Phone  
Precision Output: 1% tolerance output voltages  
available (A grade).  
Palmtop/Laptop Computer  
Personal Digital Assistant (PDA)  
Camcorder, Personal Stereo, Camera  
Low Noise: By adding a 10 nF bypass capacitor,  
output noise can be reduced to 30 µV (typical).
