Working Principles

The RT9715HGB operates as a linear voltage regulator. It takes an input voltage within the specified range and regulates it to provide a stable output voltage. The feedback pin (FB) is used to set the desired output voltage, which can be adjusted using external resistors. The enable pin (EN) controls the on/off state of the regulator. When enabled, the IC regulates the input voltage to maintain a constant output voltage. If the input voltage drops below the desired output voltage plus the dropout voltage, the regulator enters dropout mode, where the output voltage may vary.
