Microchip Technology MIC94325
The MIC94325, MIC94345, and MIC94355 Ripple Blocker™ devices are monolithic integrated circuits that provide 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 MIC94325/45/55 maintain high power supply ripple rejection (PSRR) with input voltages operating near the output voltage level to improve overall system efficiency.| Part No. | MIC94325 |

GENERAL DESCRIPTION
A low-voltage logic enable pin facilitates ON/OFF control at typical GPIO voltage levels. The MIC94325/45/55 operate from an input voltage of 1.8V to 3.6V. 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 6-pin 1.6 mm x 1.6 mm Thin DFN, the MIC94325/45/55 have a junction operating temperature range of –40°C to +125°C.
