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