Working Principle

RT9011-SGGQWC utilizes two major components, a control amplifier and a pass transistor, to regulate the output voltage. The control amplifier is designed to detect the output voltage and adjust the pass transistor accordingly to maintain the target voltage.The amplifier also has a built-in reference voltage divider in order to prevent over-voltage and over-current conditions. It accomplishes this by providing a maximum voltage limit, after which the amplifier will issue an overtemperature signal, which in turn will shut down the pass transistor and thus limit the output voltage from exceeding its maximum level.
