Microchip Technology MIC523950YMM Low Dropout Regulator

The MIC5239 is a low quiescent current, low-dropout regulator capable of delivering 500mA output with a dropout voltage of only 350mV. It supports input voltages from 2.3V to 30V and is stable with ceramic or tantalum capacitors, requiring just a 3.3uF capacitor for stability. Featuring thermal shutdown, current limit, overvoltage and reverse-battery protection, it is ideal for USB power, portable devices, and automotive electronics. Packaged in small, thermally enhanced SOIC-8, MSOP-8, and SOT-223 packages, it ensures efficient, reliable power regulation for demanding applications.
