Datasheet
General Description
The MIC94300 is an integrated load switch that
incorporates
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
set at a fixed drop (typically 170mV) from the input voltage
(V
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
junction operating temperature range of −40°C to +125°C.

... The MIC94300 comes with an active-high enable pin that allows the Ripple Blocker™ disabled. Forcing the enable pin low disables the MIC94300 and sends it into a “zero” off mode current state. In this state, current consumed by the MIC94300 goes nearly to zero. Forcing the enable pin high enables the output voltage ...
