Working Principles

The XC6121E536MR-G is a low dropout voltage regulator that uses a PNP transistor as the pass element. It regulates the output voltage by maintaining a constant voltage difference between the input and output terminals. When the input voltage drops close to the desired output voltage, the regulator adjusts the pass element to ensure a stable output voltage.
