Working Principles

The XC6124D741ER-G 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 be dissipated as heat. Conversely, when the input voltage drops below the desired output voltage, the pass element increases the resistance to maintain a stable output voltage.
