Microchip | MIC37302WU

The MIC37302WU is a 3.0 A 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 (500 mV over temperature), and low-ground current.

The MIC37302WU operates from an input of 2.25 V to 6.0 V. 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 1.5 V, 1.8 V, 2.5 V and 3.3 V. The adjustable version is capable of 1.24 V to 5.5 V.

Features of the MIC37300/01/02 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 is from –40°C to 125°C.
