Working Principles

The MAX6474TA18BD3+T 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 adjust the pass transistor's resistance and maintain a constant output voltage. The enable pin (EN) controls the regulator's on/off state, while the input voltage (IN) supplies the power. The ground pin (GND) provides the reference potential for the circuit.
