MIC94325/45/55
500mA LDO with
Ripple Blocker Technology
General Description
The MIC943x5 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
MIC943x5 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 MIC943x5 operates from an input voltage of 1.8V to
3.6V. The MIC943x5 options include fixed (MIC94345/55)
or adjustable (MIC94325) output voltages. The MIC94355
version offers an auto-discharge to discharge the output
capacitor when the part is disabled.
Packaged in a 0.84mm x 1.32mm 6-ball CSP or a 6-pin
1.6mm x 1.6mm Thin DFN, the MIC943x5 has a junction
operating temperature range of –40C to +125C.
