Working Principles

The S-1137D14-U5T1U is a linear voltage regulator that uses a PNP transistor as the pass element. It regulates the output voltage by adjusting the resistance between the input and output terminals. When the input voltage exceeds the desired output voltage, the regulator reduces the resistance to maintain a stable output. Conversely, when the input voltage drops below the desired output voltage, the regulator increases the resistance to compensate for the difference.
