Working Principles

The RT9715EGB is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage, adjusting the pass transistor's resistance to maintain a stable output voltage. When the input voltage (VIN) exceeds the desired output voltage (VOUT), the excess voltage is dropped across the pass transistor, resulting in a low dropout voltage.
