I have read in the article above that the use of a low ESR cap at the output of the LM317 voltage regulator (which is NOT a LDO regulator) can be an issue (I have not read about this problem elsewhere).

Is that really the case? If so, WHAT is the exact reason of this?

Any comment will be greatly appreciated.

Regards.
