General Description
The Micrel MIC37252 is a 2.5A low-dropout linear voltage
regulator that provides a low voltage, high current output with a minimum of external components. It offers high precision, low dropout and low ground current. The MIC37252 operates from an input voltage of 3.0V 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 an adjustable output voltage capable of 1.24V to 5.5V. Features of the MIC37252 LDO include thermal and current limit protection, and reverse current and reverse battery protection. Junction temperature range of the MIC37252 is from –40°C to 125°C. For higher currents see the MIC3730x family of LDOs.
