Working Principles

The S-1132B47-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. When the input voltage exceeds the desired output voltage, the pass element conducts and reduces the excess voltage to maintain a stable output. Conversely, when the input voltage drops below the desired output voltage, the pass element restricts the current flow to prevent the output voltage from falling too low.
