I'm building a dual-rail power supply and need to drop about 5-10 V from the rectification output. It's for powering an amp so I need low noise and about 2A therefore I opted for linear regulators. Most schematics online use a positive and negative regulator for each rail, but I was wondering if my circuit below would work using the same regulator, one on the positive rail and one on ground.
Simulating it shows the correct output voltages, but what are the drawbacks to this design vs using a negative voltage regulator for the negative rail? Does it have power or stability issues/ there must be a reason designs keep using negative regulators.
