Part Number : LP2985AIM5-4.5
Function : Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator
Package : SOT-23 Type, DSBGA 5 Pin Type
Maker : Texas Instruments
Pinouts : 
Description :
The LP2985AIM5-4.5, LP2985-N low noise linear regulator delivers up to 150-mA output current and only requires 300-mV dropout voltage of input to output. Using an optimized VIP (Vertically Integrated PNP) process, the LP2985-N delivers unequalled performance for all battery powered designs.
The LP2985-N device provides 1% tolerance precision output voltage with only 75 µA quiescent current at 1 mA load and 850 µA at 150 mA load. By adding a 10-nF bypass capacitor, the output noise can be reduced to 30 µV RMS in a 30-kHz bandwidth.
