Introduction:

SUPER-PSU is a high-performance DIY single-rail linear regulated power supply (PSU). It is basically half the dual-rail PSU σ22, and possesses the same low-noise, high-current, excellent line/load regulation, wide-bandwidth, and stability characteristics. SUPER-PSU is ideal for DIY stereo headphone amplifiers, preamplifiers, DACs, network media players, and other applications requiring a single-rail regulated PSU.

 

The circuit uses all discrete components (no integrated circuits), and features high-current MOSFETs as the output "pass" devices.

 

SUPER-PSU is derived from the σ22, which is the result of a community service project for the audiophile hobbyist. The schematic diagram is open source. The circuit design, as well as the printed circuit board layout are the work of AMB with participation from the DIY community. It is designed to be relatively easy to build, but it is not recommended as a first-time project for the beginner.
