Working Principles

The MIC2778-2YM5-TR operates as a linear voltage regulator. It takes an input voltage within the specified range and regulates it to provide a stable output voltage. The enable (EN) pin controls the on/off state of the regulator, while the feedback (FB) pin monitors the output voltage and adjusts it accordingly. The power good (PG) pin indicates whether the output voltage is within the desired range. In case of excessive heat, the thermal shutdown protection feature shuts down the regulator to prevent damage.
