Any comments on the attached schematic? It seems to me that this design would better reject common mode noise in the AC, but I don't know enough to be sure. I don't remember ever seeing such a scheme shown in a schematic, but I don't know if that means it's pointless or if that as parts count go up, a designer will forgo a 3 terminal regulator in favour of discrete components.
Is there some issue you are trying to solve here?
Not an issue, no. I am planning to build a phono preamp with poor PSRR and want the best performance regulator I can get without going to a discrete design.
