LP2985IM5-3.3

TEXAS INSTRUMENTS  LP2985IM5-3.3  固定电压稳压器, LDO, 2.5V至16V, 280mV压差, 3.3V输出, 150mA输出, SOT-23-5

The is a fixed output, micropower low noise ultra low dropout LDO regulator in 5 pin SOT-23 package. This regulator is designed for use with very low ESR output capacitors. Using an optimized VIP Vertically Integrated PNP process, the LP2985IM5-3.3 delivers unequalled performance for all battery powered designs. This regulator provides 1% tolerance precision output voltage with only 75µA quiescent current at 1mA load and 850µA at 150mA load. By adding a 10nF bypass capacitor, the output noise can be reduced to 30µVrms in a 30KHz bandwidth. The LP2985IM5-3.3 is designed to work with a ceramic output capacitor with equivalent series resistance ESR as low as 5mohm.
