MIC94300
200mA Switch
with Ripple Blocker ? Technology
General Description
The MIC94300 is an integrated load switch that
incorporates Micrel’s 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 (V OUT ) is
set at a fixed drop (typically 170mV) from the input voltage
(V OUT = V IN – 170mV). This maintains high efficiency
independent of given load conditions and currents.
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
