Microchip Technology MIC523933YM Low Dropout Regulator

The MIC5239 is a highly efficient, low quiescent current low-dropout regulator capable of providing 500mA stable output from a wide input range of 2.3V to 30V. Its ultra-low quiescent current of only 23μA makes it ideal for keep-alive power in high-voltage battery systems, USB power supplies, and portable electronics. Designed with stability for ceramic or tantalum capacitors using just a 3.3μF output capacitor, it features thermal shutdown, current limit, and reverse-battery protection, available in compact packages like SOIC-8, MSOP-8, and SOT-223.
