Working Principles

The NCP1406SNT1G is a linear voltage regulator that uses a feedback mechanism to maintain a stable output voltage. It operates by comparing the output voltage with a reference voltage and adjusting the internal circuitry to regulate the output voltage within the desired range.

When the input voltage exceeds the required output voltage, the regulator reduces the voltage difference across its internal components, resulting in a lower output voltage. Conversely, when the input voltage drops below the desired output voltage, the regulator increases the voltage difference to raise the output voltage.
