Hello
Looking to test drive a component..
Wondering if real world conditions for the THAT1253 device will work with my present power supply..
The device has a listed minimum VCC-VEE of 7V, and I have +-5 for 10V, and I am curious if this is an adequate margin.
Not in the mood to redesign my power supply if not needed.
Preceeding single ended signal voltage is 2.1Vrms and differential is 4.2Vrms from the DAC that I have.
Thanks for any advice

If you only have +-5 Volt, even that should do. Why do you want to add another regulator? Makes no sense.
I don't know your THAT1553 design, to include a C-R-C with a small voltage drop should be nice. The THAT component has a good PSRR of 90dB, so not critical at all.
For a "test" you could power it from two 9 Volt batteries. At 2.8 mA they will last quite long.

I've run the 1240-series (exactly the same part but untrimmed) down to 6V but there's little output headroom.
The positive and negative output saturation with a 2K load is 2V (each) typical 3V max.
With a 10V supply at maximum Vcesat at 2K you'll have maybe 4 to 6 V p-p available at the output.
