Working Principle

The S-1312D16-A4T2U3 voltage regulator works on the principle of linear regulation of voltage. It contains an internal PMOS field effect transistor (FET) which performs the task of regulating the output voltage. In this regulator, the PMOS FET is used to control the voltage of the output. When the input voltage varies, the PMOS FET acts as an adjustable resistor, thereby changing the output voltage. When the output voltage falls, the PMOS FET increases the resistance of the circuit, allowing more voltage to be supplied. When the output voltage rises, the PMOS FET reduces the resistance of the circuit, reducing the amount of voltage delivered.
