2x12V Regulator with Good Precision and High PSRR

PSRR at 1kHz is 114 dB.

Voltage output is +12.000V and -12.000V at all levels of input and at all loads 0-500mA.
Input voltage tested is +/-13.7V to 24V.

There are several other opamps that can be used. And a few common opamps that would not work at all conditions.
For example OPA134 can not fit. Has to be Rail to Rail output.
OPA192 is highly recommended as it has been tested in my simulator and works all the time.

What I do not know is how much noise the output is.
But I do think it is fairly clean or even very clean output.
