I am putting together an audio center based on the new Pi2 and IQaudIO DAC which is a I2S plug on for the Pi. The Pi needs 2A @ 5V and I am guessing the DAC adds another 1A, so looking at a total of ~3A @5V. I wanted to use the Salas BiB but that is only good up to 1A. Any suggestions? I want a LINEAR supply, not SMPS.
