500mA LDO with Ripple Blocker Technology
General Description
Features
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
