• How to Build a Class-D Power AmpProjects

     · The LM317 is just a part of a circuit that happens to be a 1.25V regulator, but produces a variable output. The same way the regulators in this circuit are being used to produce "non 5V" power rails. They are just used to get a power rail that is offset by 5V from another rail. But all rails are measured W.R.T. 0 volts.
