MIC37300-2.5WR

The Micrel MIC37300/01/02/03 is a 3.0A low-dropout linear voltage regulator that provides a low voltage, high current output with a minimum number of external components. It offers high precision, ultra-low dropout (≤500mV over temperature), and low ground current. The MIC37300/01/02/03 operates from an input of 2.25V to 6.0V. It is designed to drive digital circuits requiring low voltage at high currents (i.e., PLDs, DSP, microcontroller, etc.). It is available in fixed and adjustable output voltages. Fixed voltages include 1.5V, 1.8V, 2.5V, and 3.3V. The adjustable version is capable of 1.24V to 5.5V. Features of the MIC37300/01/02/03 LDO include thermal and current-limit protection, and reverse-current protection. Logic enable and error flag pins are available on the 5-pin version. Junction temperature range of the MIC37300/01/02/03 is from -40°C to +125°C.
