For an error amplifier, the stability is defined based on the response of the amplifier for a range of sine wave frequencies.
However, when we have DC-DC conversion - linear or switching, when the source is pure DC, what is the source of AC frequency at the input of the error amplifier?
For the simplest case - converting 12V to 5V using an LDO - what could be the source of AC at the input of the error amplifier because we will have pure 12V DC at the input and all along the DC supply line.
