Working Principle

The MIC49300-1.5WR linear voltage regulator works by regulating the output voltage of a power supply. It consists of a control circuit, an input voltage feedback circuit, an output voltage feedback circuit and a driver circuit. The control circuit compares the output voltage and the desired input voltage. It then adjusts the output voltage using a current mirror configuration. The input voltage feedback circuit consists of resistors and capacitors that sense the input voltage and feedback this voltage to the control circuit. The output voltage feedback circuit senses the output voltage and compares it to a reference voltage. This feedback is used to adjust the output voltage. The driver circuit is used to drive the output voltage to the desired value.
