It is impossible to adjust the voltage down below 5.6 volts under low loads. I've had better luck with the MeanWell RS-15-5, which you can adjust down below 5.2 volts under low loads, and is is a fairly constant voltage power supply all the way up to it's rated load. It's only a 3 amp supply though, but it was perfect for my application.</p>

(For example, use the 5V pin on an arduino instead of the DC jack.)<p>The spec power efficiency of the 5V supply is 80%, much better than a linear regulator.</p></p>
