Simple Low Ripple PSU for DAC

Power supplies are needed for every type of electronic equipment and are one of the most important component in a audio electronic equipment such as a DAC.

This project illustrate how can you build a simple low cost unregulated power supply that you can use for a DAC that have an unregulated power supply input from 15V to 18V and a current  < 1500mA.
