Working Principles

The MIC5209BU TR is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the reference voltage with a fraction of the output voltage and adjusting the pass transistor accordingly. This feedback mechanism ensures a stable output voltage despite variations in input voltage and load conditions.
