These were to be read (sorta) together:"Usually there is a simple wiring diagram to follow..........."

this HAS many (and what I thought 'were diagrams that' didnt apply to me needs/application) <-- added clarity between single quotes, and typo fixed)
- as in many diagrams.. with many configurations..
Whew! That was a tough sentence to parse!! But I think I finally figured out that you're trying to say. Yes, the datasheet covers a number of different variations, and such datasheets can be a bit daunting. Hard to find the sections that are relevant to your particular version.
I read this line as well:
"Please attach a capacitor (greater than 0.33μF) between the Vcc and GND"And the diagram directly under it as well.. (using a 22uF cap on the output)
- which I believe is the same cap value I used when I looked at this datasheet originally... (again not at home to confirm, but this is my current stance/belief)
So, it sounds like you need to learn about the concept of ideal vs reality. The ideal capacitor has merely capacitance. The real world capacitor has, along with it's inherent capacitance, also resistance ["ESR"] and a certain amount of inductance. The inductance component is more prevalent in a capacitor that is manufactured by rolling the "foils" into a cylinder. For instance an Electrolytic Capacitor. But that's an aside.
All capacitors have ESR, and this is a parameter that is just as important as capacitance, in this particular instance. In other words, not just any 0.33μF cap is suitable for this application. It needs to have the correct capacitance AND an ESR that's within the range of Stable Operation.
