Working Principles

The S-1132B37-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 pass element reduces the resistance, allowing excess voltage to drop across it. This maintains a stable output voltage within the specified range.
