Seems like a good device, but the datasheet I found was marked end of life.

They’re usually cheap enough to buy and try - full load voltage test with varying input voltages to dropout will soon show dodgy ones. There’s no formula for spotting fakes.
Same issues will apply though with any regulator that has to dump a lot of voltage with the amount of heat they’re required to dissipate. If you got it working fine with the buck converter do you need to pursue it any further? Other than getting 6.3VDC instead of 6V.
No, I'm good. Just a few others jumped into the conversation and I figured I would learn something.
Couldn’t hurt to have a regulator that gives exactly 6.3V DC after the buck converter rather than 6V. This system certainly covers any changes to mains voltage that could cause dropout or overheating. I’d be looking at a heatsink for the regulator regardless.
Well, that does bring me to another question, now that you mention it. Why do we use 6.3VDC, when it's spec'd for 6.3VAC? Isn't the relative energy of DC much higher than the energy of AC? Meaning we get the same amount of heat with lower DC voltage than is required for AC?

AC RMS = Heating value = DC
*facepalm... my AC meter is reading RMS. Your answer was exactly what I was looking for though, thank you.
That’s why there are 6.3V regulators I guess
