Working Principle

The MIC29312WT is an adjustable shunt type, low dropout linear voltage regulator. It works by diverting excess current through a shunt resistor, which reduces the voltage across the power supply source and maintains the their set voltage. It also utilizes an internal reference voltage to detect any changes in the output voltage and adjusts the output current accordingly. The result is a regulated output voltage that does not vary with line and load changes.
