Working Principle

The RT9058-C0GV linear voltage regulator comprises a voltage reference, error amplifier, pass transistor and a power output. The main component of the regulator is the error amplifier, which compares the output voltage to the reference voltage and when a difference is detected it sends an appropriate signal to the pass transistor. This causes the transistor to adjust the output voltage to match the reference voltage, thus providing a precise output voltage.

The voltage reference is used to set the desired output voltage. A voltage divider is used to provide the reference voltage to the error amplifier. The output of the reference is then compared to the output of the pass transistor to ensure that the output from the pass transistor is equal to the reference voltage. The pass transistor is usually a field effect transistor (FET) which can be easily adjusted for output voltage. Once the output voltage is reached, the error amplifier turns off the gate of the FET, thus shutting down the supply and maintaining the output voltage.
