Hi As with anything else it’s a matter of “what’s in your wallet”.
The parts you are after are called voltage references rather than voltage regulators. You can get them well down into the low ppm’s / C or lower. The cutoff is more a function of “do you want to spend $100 or not” rather than a specific level you simply can’t get to.
