Working Principle

The TPS73216DBVTG4 operates on the principle of linear regulation, meaning that the output voltage deviates minimally from the desired voltage. This is achieved by allowing a controlled amount of current to pass through the device. The amount of current allowed is determined by a feedback loop and the control signal, which is generated from the output voltage.The output voltage is regulated by two main components, the internal PNP transistor and the error amplifier. The internal PNP transistor is the main power delivery element of the regulator and is connected in series with the output voltage. The error amplifier monitors the output voltage and generates a control signal to the base of the transistor if the output voltage starts to deviate from the desired voltage. By varying the current flow, the output voltage of the regulator is stabilized.
