Abstract

PURPOSE:To widen an allowable range to the fluctuation of the input voltage of a load control circuit by connecting a collector and emitter circuits between a power source and a load, and providing a transistor for feeding back a voltage from the load and amplifying in a base to lower a lost voltage in the load control circuit. CONSTITUTION:A motor driver 6 is constituted of the transistor Tr4, in the emitter is connected to the power source 1 and the collector is connected to a motor and the transistor Tr5 in which the emitter is connected to the connecting point of resistances R4, R5, the base to the connecting point of resistances R7, R8, and the collector to the base of the transistor Tr4. The fluctuation of the voltage of the power source 1 appears as a voltage difference (difference of VP and VQ) between the base and the emitter of the transistor Tr5 and this is fed to the collector potential of the transistor Tr5, namely, to the base potential of the transistor Tr4. Therefore, the amplification degree of the transistor Tr4 is changed as circumstances require so as to constantly stabilize a voltage impressed to the motor 2 and the influence due to the fluctuation of the voltage of the power source 1 can be neglected.
