MIC94300 200mA Switch with Ripple Blocker? Technology General Description Features The MIC94300 is an integrated load switch that ? 1.8V to 3.6V input voltage range incorporates Micrel?s Ripple Blocker ? active filter ? Active noise rejection over a wide frequency band technology. The MIC94300 provides high-frequency ripple ? >60dB from 40kHz to 5MHz attenuation (switching noise rejection) for applications ? Rated to 200mA output current where a switching noise cannot be tolerated by sensitive ? Current-limit and thermal-limit protected downstream circuits such as in RF applications. A low- voltage logic enable pin disconnects the pass element and ? Ultra-small 0.88mm x 0.88mm 4-ball CSP ? places the MIC94300 into a low current-shutdown state ? 1.2mm x 1.6mm, 4-pin Thin MLF when disabled. ? Logic-controlled enable pin The MIC94300 operates from an input voltage of 1.8V to ? ?40?C to +125 ?C junction temperature range 3.6V, allowing true load switching of low-voltage power rails in any electronic device. The output voltage (V ) is OUT set at a fixed drop (typically 170mV) from the input voltage Applications (V = V ? 170mV). This maintains high efficiency OUT IN ? Smart phones independent of given load conditions and currents. ? Tablet PC/notebooks and webcams Packaged in a 0.88mm x 0.88mm 4-ball CSP or 4-pin ? 1.2mm x 1.6mm Thin MLF package, the MIC94300 has a ?
