MIC94305
500mA Switch
with Ripple Blocker™ Technology
General Description
Features
The MIC94305 is an integrated load switch that
incorporates Micrel’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 170mV) from the input voltage
(VOUT = VIN – 170mV). This maintains high efficiency
independent of given load conditions and currents.
The MIC94305 is packaged in a 6-ball 0.84mm x 1.32mm
CSP package, or 6-pin 1.6mm x 1.6mm Thin DFN
package, and has a junction operating temperature range
of −40°C to +125°C.
