The MIC4575-5.0WU is a step-down (buck) switching regulator capable of delivering up to 1A of output current. It operates at a fixed frequency of 200 kHz, which allows for a reduction in the size of output filter inductors compared to lower frequency regulators. The input voltage range is wide, from 4V to 24V, and it provides a fixed output voltage of 5V with a maximum output voltage tolerance of ±3% under specified line and load conditions. This regulator features low shutdown current consumption of less than 200 µA and offers high efficiency, typically around 75%. It includes built-in protections such as thermal shutdown and cycle-by-cycle current limiting. The MIC4575 series is designed to require minimal external components, making it suitable for various applications, including battery chargers and on-card switching regulators. It is available in TO-220 and DDPAK packages, suitable for industrial temperature ranges.
