する電流制限回路。 A current comprising: a first transistor that adjusts the level of a DC input signal and outputs it; and a second transistor that is driven to switch according to the current flowing through the first transistor and limits the current flowing through the first transistor. In the limiting circuit, the first and second transistors are arranged close to each other so that the heat generated by the first transistor reduces the current value required for switching drive of the second transistor. current limiting circuit.
