ABSTRACT:
A control transistor (3) is connected between a power supply terminal (1) and an output terminal (19). The base bias of the control transistor (3) is controlled by bias control transistors (12, 13), thereby the output voltage is maintained at a constant value. An overcurrent state is detected by a current control detecting transistor (22), and the base bias of the control transistor (3) is controlled by the bias control transistors (12, 13), so as to prevent the overcurrent. The current control detecting transistor (22) further detects the time when the potential of the output terminal (19) becomes approximately 0 V by, e.g., short-circuiting of a load, so as to control the base bias of the control transistor (3) through the bias control transistors (12, 13), thereby the current to the load is decreased to a value considerably smaller than a limited value for preventing the overcurrent.
