Working Principles

The MAX761ESA+T is a voltage regulator IC that regulates the input voltage to a desired output voltage level. It achieves this by using an internal reference voltage and feedback mechanism. The input voltage is supplied to the Vin pin, and the regulated output voltage can be obtained from the Vout pin. The feedback pin (FB) is used to adjust the output voltage by connecting an external resistor divider network. The enable pin (EN) allows for power management control, enabling or disabling the regulator as needed.
