Abstract
PURPOSE: To decrease electric current load in control transistors, by connecting control resistance in series to the control transistors, and making short-circuited switches which are connected to the both ends of this control resistance to be ON and OFF, in accordance with load current.
CONSTITUTION: Output voltage is stabilized by driving control transistors 13 which are connected among input Vin and Vout with stabilized circuit 14. Limiting resistance 21 is connected in series to above-mentioned control transistors 13, switching transistors 22 are connected among both ends of this limiting resistance 21, and the switching transistor 22 is OFF, when input voltage is big, and is ON, when input voltage is small. Thus, suppression of excess current is made by limiting resistanc, and electric load of the control transistors 13 is made to be decreased.
