Default Ultra Low noise voltage regulator IC till 80Volts?

There are couple of TI voltage regulators with noise floors as low as 3 to 14uV but the limit is upto just 35V after that there is another one with 100V but only for positive rail there is nothing for negative rail substitute.

Are there any other vregs with low output noise?

Can the 100v v-reg be turned upside down and run as a neg-v-reg?

Here is another thread that rythmsandy started yesterday that contain a part number that goes to 36V input and has a negative regulator equivalent that is 16uV of noise. (the positive one mentioned is 4uV):

Use split supplies and ground the positive output for the negative regulator.
