A.
[Cause (1)] Input-output wiring:
Long wiring or wiring where the input and output are not isolated lead to the generation of noise.
[Cause (2)] The input voltage is low:
The ripple and noise increase when the input voltage becomes low.
［Cause (3)］ The load current is high：
The ripple and noise increase when there is excessive load.
