Working Principles

The MAX668EUB+TG24 operates as a linear voltage regulator. It takes an input voltage from the VIN pins and regulates it to provide a stable output voltage at the VOUT pins. The feedback pin (FB) is used to adjust the output voltage by connecting external resistors. The enable pin (EN) allows the user to control the regulator's operation.

When the input voltage exceeds the desired output voltage, the IC reduces the voltage difference across it, resulting in a lower dropout voltage. This helps maintain a stable output voltage even when the input voltage is close to the desired output voltage.
