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.
Additional Features
1.8V to 3.6V input voltage range
Active noise rejection over a wide frequency band: >60dB from 40kHz to 5MHz
Rated to 200mA output current
Logic Controlled enable pin
Current-limit and thermal-limit protected
-40°C to +125°C junction temperature range
