MIC94310
200mA LDO with
Ripple Blocker? Technology
General Description
The MIC94310 Ripple Blocker? is a monolithic integrated
circuit that provides low-frequency ripple attenuation
(switching noise rejection) to a regulated output voltage.
This is important for applications where a DC/DC switching
converter is required to lower or raise a battery voltage but
where switching noise cannot be tolerated by sensitive
downstream circuits such as in RF applications. The
MIC94310 maintains high power supply ripple rejection
(PSRR) with input voltages operating near the output
voltage level to improve overall system efficiency. A low-
voltage logic enable pin facilitates ON/OFF control at
typical GPIO voltage levels.
The MIC94310 operates from an input voltage of 1.8V to
3.6V.
Packaged in a 0.88mm × 0.88mm 4-ball CSP, a 4-pin
1.2mm × 1.6mm Thin DFN, or a 5-pin SOT-23, the
MIC94310 has a junction operating temperature range of
–40 ° C to +125 ° C.
