Microchip MIC94325YMT-TR, 1 Linear Voltage, Voltage Regulator 500mA, 1.2 → 3.4 V 6-Pin, DFN

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.
