Working Principle

The RT9011-CGGJ6 operates by comparing the reference voltage to the feedback voltage in order to adjust the equivalent resistance of the output voltage. It is composed of an error detection circuit, a reference voltage reference circuit, an output voltage regulation circuit, an overvoltage protection circuit, and a frequency compensation circuit.

In operation, the voltage difference between the reference voltage and the feedback voltage is compared and sends a signal to the output circuit. The output voltage will then be adjusted accordingly. This process is repeated in a feedback loop, so that the output voltage remains precisely regulated. The overvoltage protection circuit will protect the circuit by limiting the output voltage.
