Device Overview

Summary

The MIC94300 is an integrated load switch that incorporates Ripple Blocker™ active filter technology. The MIC94300 provides high-frequency ripple attenuation (switching noise rejection) for applications where a switching noise cannot be tolerated by sensitive downstream circuits such as in RF applications. A low-voltage logic enable pin disconnects the pass element and places the MIC94300 into a low current-shutdown state when disabled.

The MIC94300 operates from an input voltage of 1.8V to 3.6V, allowing true load switching of low-voltage power rails in any electronic device. The output voltage (VOUT) is set at a fixed drop (typically 170mV) from the input voltage (VOUT = VIN– 170mV). This maintains high efficiency independent of given load conditions and currents.
