Voltage regulation circuit 12V to 5V in 5A range

[Demon]

Wasted so much time trying to figure out why I STILL had a lot of ripples with the LM1084.

I checked directly on the wall adapter:



GIGO; can't expect the LM1084 to do miracles with that.


So I pulled out a 12V-5A Fqcmogu AL-1250 adapter (no idea what it's for):



Definite improvement.


This is the LM1084-5V running at 5.0V (LED strips and whatnot):




This is the LM1084-ADJ running at 5.2V (PIC, LCDs and other ICs), note that is had less ripples as stated in the specs:
