The working principle of the NCP703SN28T1G voltage regulator is based on an internal current source, composed of a PNP bipolar transistor. When the input voltage to the regulator is greater than the regulated output voltage, the internal current source will begin to flow, causing a voltage drop proportional to the load current. This voltage drop is essentially the voltage regulation of the NCP703SN28T1G regulator. Additionally, the device features an internal loop that is used to adjust the internal reference voltage of the device, allowing it to stay regulated at the output voltage regardless of any changes in the input voltage.

The NCP703SN28T1G provides many benefits and features. It is designed to consume very low power, minimize the stress on power sources and extend the battery life. Its wide input voltage range and high PSRR make it suitable for a wide variety of applications, and its high accuracy output regulation allows it to provide a stable power supply to delicate circuits and devices. Furthermore, it features an input protection diode and an output protection diode to protect the device from short circuit and over-voltage conditions.
