The MIC37100, along with the MIC37101 and MIC37102, are 1A low-dropout linear voltage regulators designed for low-voltage, high-current output from a compact package. Utilizing Micrel’s Super βeta PNP pass element, these regulators offer low dropout voltage and low ground current. They are ideal for PC add-in cards converting 5V to 3.3V, 3.3V to 2.5V, or 2.5V to 1.8V. The MIC37100 provides overcurrent limiting and thermal shutdown protection, ensuring reliable operation in various industrial applications.
