..............
I intend to do load transients to an LDO. I want to make a load step at the output for several current value and combinations.
What you mean by pulse shape? If it is a pulse you are I directly saying that it it a pulse, like square-wave.
What you mean by transient duration duration? You mean the step duration? Like rise/fall time? I would say 10ns, 100ns,1us.
In addition to this I want to do the same to an amplifier (two stage) and to class AB amplifier.
