Working Principle

The S-13R1D20-A4T2U3 linear voltage regulator chip works by converting an input voltage into a constant, regulated output voltage. It does this by using an integrated linear voltage regulator circuit that uses a reference voltage internally. When the input voltage is higher than the reference voltage, the regulator circuit will increase the impedance of the pass transistor and reduce the output voltage. Conversely, when the input voltage is lower than the reference voltage, the transistor impedance will be decreased and the output voltage will be increased. This process is repeated until the output voltage is equal to the reference voltage, and the output voltage will remain constant regardless of any subsequent changes in the input voltage.
