Working Principle

The NCP703MX30TCG is a three-terminal adjustable voltage regulator, which means it uses a three-terminal configuration to control the output voltage. It consists of a voltage reference, an error amplifier, a series pass device (typically a MOSFET), and a control circuit. The voltage reference provides a constant-voltage reference, and the error amplifier is used to compare it with the output voltage and generate any necessary corrections. The series pass device is then used to control the current flow, and the control circuit is used to adjust the duration and current flow of the series pass device. This way, the output voltage of the regulator can be adjusted through varying the duration and current flow of the series pass device.
