Yes.

Nope.

That utterly mangles the real story.

That utterly mangles the real story.

What you actually mean is that the no load voltage can be
1.2V but that it can't deliver that voltage with a  normal load.

That mangles the real story utterly.

And with that in spades.

And so does that.

And so is that.
