Working Principles

The MIC2774H-28BM5-TR is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage to control the pass transistor's conduction. When the output voltage deviates from the desired value, the regulator adjusts the pass transistor's resistance to maintain a stable output voltage.
