Greetings,
I'm not a circuit designer. But I'm attempting to configure and assemble a DIY audio equipment design. I have looked all over for details on how to build a very low noise linear power supply that I would like to use with a SPDIF board which I intend to use in a music streamer. The regulated output of the supply should be 5VDC +10%/-2% and the load output current may vary from 75 to 120mA. I like the noise to be very low, say less than 200nV. The input voltage should be nom. 9VAC. I would be very pleased if someone could point me in the direction of a circuit diagram that I could use for this.
