5V PSU for Eurorack

Eurorack 5V Regulator PCB

The Eurorack 5V Regulator PCB is a compact PCB-only solution designed to generate a regulated +5V rail from an existing +12V supply and distribute it to your Eurorack power bus. It provides a simple and efficient way to add +5V support to modular systems that require it.

Key Features

• PCB-only Eurorack 5V regulator
• Regulates +12V down to +5V
• Distributes +5V directly to the Eurorack power bus
• Simple, easy-to-build design
• Compact footprint for flexible case integration

Power Regulation & Usage

This 5V regulator PCB is intended for systems where a +5V rail is required but not provided by the main power supply. Once installed, it converts +12V to +5V and feeds the regulated voltage into the power bus for compatible modules.

Important: Although the PCB regulates voltage, all current drawn from both the +5V and +12V rails is supplied by the +12V source. Be sure to calculate total system current carefully and ensure your +12V power supply can handle the combined load.

DIY Build Notes

This DIY Eurorack 5V regulator PCB is designed to be straightforward to assemble and does not include components. Builders can populate the board with components of their choice based on system requirements.
