Working Principles

The S-1135C19-M5T1U 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 pins. When the input voltage exceeds the desired output voltage, the pass element reduces the resistance to maintain a stable output. Conversely, when the input voltage drops below the desired output voltage, the resistance increases to compensate and provide a constant output voltage.
