Working Principles

The MAX6466UR46+T is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the reference voltage with the feedback voltage derived from the output. The pass transistor adjusts its resistance to maintain a constant output voltage, compensating for changes in load and input voltage.
