It contains some very interesting setups.I read this article twice and is very juicy imo. The problem is that is lacks last page(s).
You have a nice article, but for beginners and veterans, this application note for the UA723 I found informative on learning the ins and outs of voltage regulators.Really? You want to seriously study that and spend many hours doing so?
You picked probably the least accesible text.
Not to brag, but start with the superreg article in the diyaudiostore.
That is written for people who are relatively new to regulators, to get up to speed easily and quickly, math-free.
