For one of my projects, I have just little space to built my components in.
As I have to power an Up2Stream Mini v3, I need a 5 Volt, 1 Amp AC-to-DC power supply.
I have tried several AC/DC 230 to 5v converters. All af them were switching power supplies. But in audio applications, they all cause ripple noise.
Therefor I want to try a linear power supply, but it has to be very small. Preferably close to the size of a USB power wall plug, like the iPhone power supply, or the one delivered with the Arylic S10. Example see picture.
Anyone who knows where to find that?
