LP2985AIM5-4.5 Datasheet PDF – Ultra-Low-Dropout Regulator

Part Number: LP2985AIM5-4.5

Marking : LA7A

Function: Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator

Package: SOT-23, DSBGA 5 Pin type

Manufacturer: Texas Instruments


LP2985AIM5-4.5 datasheet



The LP2985AIM5-4.5 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.



1. Input Voltage Range: 2.5 V to 16 V

2. Ultra Low-Dropout Voltage

3. Ensured 150 mA Output Current

4. Requires Minimum External Components

5. Stable With Low-ESR Output Capacitor
