MIC5355

MIC5355/6 Dual 500mA µCap Low Dropout, Micropower Linear Regulator General Description The MIC5355/6 is an advanced dual, micropower, low dropout linear regulator. The MIC5355/6 provides low quiescent current operation, using only 70μA with both outputs enabled making it ideal for battery-powered systems. In shutdown, the quiescent current drops to less than 1µA. The MIC5355/6 provides two independentlycontrolled high-performance 500mA LDOs with typical dropout voltage of 350mV at rated load. In addition, the MIC5355/6 is optimized to provide fast load and line transient performance with low-ESR ceramic output capacitors, requiring a minimum of only 2.2µF. The MIC5356 also incorporates an active discharge feature when the part is disabled that switches in a 30Ω load to pull down the output of the regulator. The MIC5355/6 is available in fixed output voltages in a thermally-enhanced 8-pin ePad MSOP package or 8-pin ePad 3mm x 3mm MLF® package. Data sheets and support documentati...
