Working Principles

The MAX6475TA15BD3+T is a low-dropout voltage regulator that operates by comparing the feedback voltage at the FB pin with a fixed internal reference voltage. It adjusts the pass transistor to maintain a stable output voltage, even when the input voltage varies or the load changes. The enable pin allows the regulator to be turned on or off, conserving power when not needed. The thermal shutdown and current limit features protect the regulator and the connected circuitry from excessive heat and current.
