Working Principles

The MIC5203-3.6YM4-TR utilizes a combination of internal circuitry, feedback mechanisms, and pass elements to regulate the output voltage. When the input voltage exceeds the desired output voltage, the regulator reduces the excess voltage through the pass element. Conversely, if the input voltage drops below the desired output voltage, the regulator compensates by increasing the voltage through the pass element. This closed-loop feedback mechanism ensures a constant output voltage.
