MIC94310

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 lowvoltage 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 WLCSP, 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.
