Working Principles

The MIC5201BM is a linear regulator that uses a PNP pass transistor to regulate the output voltage. It operates by comparing the reference voltage with a fraction of the output voltage, adjusting the pass transistor accordingly to maintain a stable output. The enable pin allows for easy on/off control of the regulator.
