The protection circuit comprises an excessive current detector for detecting an excessive collector current of the output NPN transistor, an excessive temperature detector for detecting an excessive temperature of the output transistor, and an OR gate for taking a logical sum of output signals of the detectors. According to the output signal of the OR gate, a base current of the control NPN transistor is controlled, so that a base current of the output transistor is kept below a predetermined value.
