MIC94305YMT-T5

MIC94305 500 mA Switch with Ripple Blocker Technology Features General Description 1.8V to 3.6V Input Voltage Range The MIC94305 is an integrated load switch that incorporates Microchips Ripple Blocker active filter Active Noise Rejection Over a Wide Frequency technology. The MIC94305 provides high-frequency Band ripple attenuation (switching noise rejection) for - >60 dB from 40 kHz to 5 MHz applications where switching noise cannot be tolerated Rated to 500 mA Output Current by sensitive downstream circuits, such as RF Current-Limit and Thermal-Limit Protected applications. A low voltage logic enable pin 1.6 mm 1.6 mm 6-Pin Thin DFN disconnects the pass element and puts the MIC94305 in a low current shutdown state when disabled. Logic-Controlled Enable Pin 40C to +125C Junction Temperature Range The MIC94305 operates from an input voltage of 1.8V to 3.6V, allowing true load switching of low voltage Applications power rails in any electronic device. The output voltage Smartphones (V ) is set at a fixed drop (typically 170 mV) from the OUT Tablet PC/Notebooks and Webcams input voltage (V = V 170 mV). This maintains OUT IN high efficiency independent of given load conditions Digital Still and Video Cameras and currents. Video Conferencing The MIC94305 is packaged in a 6-pin 1.6 mm x 1.6 mm Barcode Scanners Thin DFN package and has a junction operating Global Positioning Systems temperature range of 40C to +125C.
