MIC94310-SYM5-T5

MIC94310 200 mA LDO with Ripple Blocker Technology Features General Description 1.8V to 3.6V Input Voltage Range The MIC94310 Ripple Blocker is a monolithic integrated circuit that provides low-frequency ripple Active Noise Rejection Over a Wide Frequency attenuation (switching noise rejection) to a regulated Band: >50 dB from 10 Hz to 10 MHz at 200 mA output voltage. This is important for applications where Load a DC/DC switching converter is required to lower or Rated to 200 mA Output Current raise a battery voltage, but where switching noise Fixed Output Voltages cannot be tolerated by sensitive downstream circuits Current-Limit and Thermal-Limit Protected such as in RF applications. The MIC94310 maintains 1.2 mm x 1.6 mm 4-Pin TDFN high power supply ripple rejection (PSRR) with input voltages operating near the output voltage level to 5-Pin SOT-23 improve overall system efficiency. A low-voltage logic Ultra-Small 0.88 mm x 0.88 mm WLCSP enable pin facilitates ON/OFF control at typical GPIO Logic-Controlled Enable Pin voltage levels. -40C to +125C Junction Temperature Range The MIC94310 operates from an input voltage of 1.8V Applications to 3.6V. Smartphones/Smart Books Packaged in a 4-pin 1.2 mm 1.6 mm TDFN, a 5-pin Tablet PC/Notebooks and Webcams SOT-23, or a 0.88 mm 0.88 mm 4-Ball WLCSP, the MIC94310 has a junction operating temperature range Digital Still and Video Cameras of -40C to +125C.
