PROBLEM TO BE SOLVED: To provide a power reduction circuit that activates a low load circuit by reducing power consumed by transistors(TRs). SOLUTION: Current flowing through a TR 4 from its collector to its emitter activates a drive circuit 5 to apply a voltage across a Zener diode 6 to apply a constant voltage to the emitter of the TR 4. This constant voltage is applied to the low load circuit 7, which consumes power. |
