Hey Guys,
Having an issue with a power circuit I built for some audio equipment. Essentially what the circuit does is take a 12V input, and converts it to 5V using a switching regulator to one output. The other output is just supposed to be a passthrough, whatever the input is, is what the output of the second jack will be. Everything works properly when using either the 12V output or 5V independently. However, when using both at the same time there seems to be some hum introduced into the circuit. I am posting my wiring diagram, any help is greatly appreciated.
