TI LP2985IM5X-5.0/NOPB

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