Working Principles

S-1112B33PI-L6STFG operates based on the principle of linear voltage regulation. It uses a pass transistor to regulate the output voltage by adjusting the resistance between the input and output terminals. When the input voltage exceeds the desired output voltage, the pass transistor reduces the resistance, allowing excess voltage to be dissipated as heat. Conversely, when the input voltage drops below the desired output voltage, the pass transistor increases the resistance to maintain a stable output voltage.
