Working Principles

The S-1132B49-U5T1G 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, maintaining a constant voltage difference (dropout voltage) across the regulator.

When the input voltage exceeds the desired output voltage, the pass element conducts, allowing current to flow from the input to the output. As the output voltage reaches the desired level, the pass element adjusts its resistance to maintain a stable output voltage.
