Device Overview

Summary

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 less than 1µA. The MIC5355/6 provides two independently controlled 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.
