Working Principles

The MAX6474TA25AD3+T is a voltage regulator that regulates the output voltage to a fixed 2.5V, regardless of variations in the input voltage. It achieves this by utilizing a low dropout design, which minimizes the voltage difference between the input and output. The regulator operates by comparing the feedback voltage at the FB pin with an internal reference voltage. Any deviation from the desired output voltage is corrected by adjusting the internal circuitry.
