Working Principles

The MAX8880ETT+T is a low-dropout linear regulator that regulates the output voltage by maintaining a constant voltage difference between the input and output. It achieves this by using a pass transistor to control the flow of current from the input to the output. The feedback pin (FB) is used to set the desired output voltage, which is compared to an internal reference voltage. Any deviation from the set voltage is corrected by adjusting the pass transistor's resistance.
