Re: Split rail regulated power supply

Doug,

In this case, I assume that by 'shunt regulator' you mean Alan's SuperReg.

Yes, you can 'stack' them, to create your +/- regulated supply. The right way to do this, is to use an HV transformer with identical dual secondaries, each with its own bridge rectifier, first filter cap, and then regulator module.

For the positive side, the reg's ground is connected to circuit ground, and the output is taken from the reg's output (as is normal). For the negative side, the reg's output is connected to circuit ground, and the output is taken from the reg's ground terminal.
