产品说明

The 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 unequaled 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 µVRMS in a 30-kHz bandwidth.

The LP2985-N is designed to work with a ceramic output capacitor with equivalent series resistance (ESR) as low as 5 mΩ. The devices are available with fixed output voltage from 2.5 V to 6.1 V. Contact Texas Instrument Sales for specific voltage option needs.

The smallest SOT-23 and DSBGA packages are available for absolute minimum board space.
