Pot calling the kettle back. The difference between you telling me I was wrong, and me telling the other guy he was wrong, and the other guy telling me I was wrong is that of the three of us, only I was on topic.

The topic is literally asking why anyone would adjust a fixed reg like a 7815 instead of using an "adjustable" 317. NareshBrd and myself gave valid answers why. The person who is wrong and dragging things off topic is you.Pot calling the kettle back.

Actually, it's volt, ampere, watt, etc. Units are not capitalized when written out. Also, there should be a space between the number and the unit. So it'd be 15 V DC. Just as you would write fifteen volt DC not fifteenvolt DC.BTW it is Volt, Ampère, Watt etc. so 15V DC. Writing stuff right on a technical forum is fun. You should try it!
Just saying. 😉

Me and NIST ( full specs of SI units standard) disagree. All units named after a human (Volt, Watt, Ampere, Kelvin, etc) are capitalized. All magnitudes above 10e6 are capitalized. The others are not. As exception are all the computer units that follows an independent standard.

I'm somewhat baffled by your post, because the document you linked to says the exact opposite of what you claim it does. Did you actually read it? It's ampere, volt, kelvin, etc.
Page 15, name of units is in caps (A, V, K, N, Pa, J, F, S, T, Wb ...) when is named after a human.
Are you joking? Actually LOOK at the second column of your table. Where are the NAMES of units capitalized? It even says "names" in the second column heading!
Pass also use this technique in the differential pre-amp stage of their integrated amplifiers (likely all their pre-amps).
I’m a DIYer, so the four 78xx went the journey, replaced by discrete SparkoS Labs. regulators to very good effect.
