@2:26 That Schematic (no. 3) will not work! It will deliver only 0,6V. You have to e. g. exchange the Zener diode with the 500 Ohms resistor to get it working.
Are you referring to the transformer output? If so it's because the scope division is higher for tranformer probe. As there is lots of ripple. So I have to use higher division to fit in the screen.

Yep. Your 100%tight. I mixed up the resistor and zener diode places. Tnx for correction.
Why the power supply ripple is lower than any of the regulator outputs? Regards.
