The project is an electronic circuit for regulating negative voltage (Negative Voltage Regulators).

This is a complete PCB project for stabilizing negative voltage, which includes a professional design of a printed circuit board (PCB) with all the files necessary for manufacturing and assembly. The circuit is designed to provide a stable and reliable negative voltage to electronic components, while protecting the system from voltage fluctuations. Suitable for use in analog systems, symmetrical power supplies, DIY projects and studying electronics.

The package includes everything you need to manufacture and assemble it:

Electrical schematic (PDF, PNG, SVG, JSON) – shows the connection of the components.

PCB Layout – the printed circuit board drawing, including a 3D file (OBJ/DXF).

Gerber Files + Pick & Place – standard files for manufacturing the board in the factory.

BOM (Bill of Materials) – the list of components needed to assemble the circuit.

Altium compatibility files (PCBdoc, Schdoc) – allow you to work on it in Altium as well.

1. Schematic – Electrical schematic

• Schematic_negative-voltage-regulators_2026-04-02.pdf / .png / .svg – Circuit diagram in various formats.

• SCH_negative-voltage-regulators_2026-04-02.json – Source file from the software (EasyEDA), editable.

This folder contains the electrical schematic of the project – how all the components are connected.

2. Layout (Schematic) – PCB layout

• PCB_PCB_negative-voltage-regulators_2_2026-04-02.pdf / .png / .svg – Presentation of the PCB itself (printed circuit board) in various formats.

• PCB_PCB_negative-voltage-regulators_2_2026-04-02.json – Source file of the layout from the software.

This folder contains the printed circuit board design – how the components are laid out and how the conductors are connected.

3. Gerber files – manufacturing files

• Gerber_negative-voltage-regulators_PCB_negative-voltage-regulators_2_2026-04-02.zip – a ZIP file that contains all the Gerber files in the standard format for PCB factories.

• BOM_negative-voltage-regulators_2026-04-02.csv – a list of components (Bill of Materials).

• PickAndPlace_PCB_negative-voltage-regulators_2_2026-04-02.csv – a file for automatic assembly machines that shows where each component is placed on the board.

This is the most important folder for manufacturing – with it you can order the circuit from any PCB factory.

4. CAD files – 3D and CAD files

• OBJ_PCB_negative-voltage-regulators_2_2026-04-02.zip – 3D model of the PCB in OBJ format.

• PCB_negative-voltage-regulators_2_2026-04-02.dxf – CAD file in DXF format suitable for engineering drawing programs.

This folder is intended for 3D viewing or use in CAD programs.

5. EasyEDA to Altium – Files for Altium Designer

• Sheet_1_2026-04-02.schdoc – Schematic file compatible with Altium software.

• PCB_negative-voltage-regulators_2_2026-04-02.pcbdoc – PCB file compatible with Altium software.

Allows those working with Altium Designer to open, edit and continue work on the project.

Summary:

Inside the ZIP is everything you need:

• Schematics (electrical drawing)

• PCB layout

• Gerber files for manufacturing + BOM + Pick & Place

• CAD files for 3D

• Altium compatibility files

In other words – a completely ready project from A to Z: both for documentation, for manufacturing, and for editing in various programs.
