The working principle of the MIC39102BM is based on a band gap voltage regulator circuit. This circuit produces a reference voltage that is used to control the output voltage. The device has two control terminals, one for the reference voltage and one for the output voltage. The reference voltage is determined by an external resistor connected to the REF terminal, while the output voltage is adjusted by the voltage at the CTRL terminal. The voltage at the CTRL terminal is connected to the output of a voltage divider. The voltage divider ratio is determined by two external resistors. The output voltage is set by adjusting the voltage divider ratio, which changes the voltage at the CTRL terminal.
