Regulator
About the Regulator PCB
Regulator is an open source PCB design by pravsels, published on GitHub. It is a 2-layer board measuring 31.6 × 9.3 mm, with 10 components from 9 distinct parts.
Other key parts include the TPS79333-EP. By type, the board carries 3 capacitors, 2 connectors, 2 diodes, 2 resistors and 1 IC.
From the project
pcb designs of simple circuits
- J1, J2 (Conn01x02)** - Simple 2-pin power connectors - Handle power in (5V) and out (3.3V) - Ground return path for current
- C2 (2.2μF) - Main output stabilization - Supplies current during load changes - Maintains 3.3V while regulator adjusts - Required for regulator stability
- C3 (0.01μF) - Catches high-frequency output noise - Partners with C2 for better stability - Fast response to small fluctuations

Regulator: common questions
How big is the Regulator PCB?
The Regulator measures 31.6 × 9.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Regulator?
10 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the Regulator design files?
From the pravsels/pcb_designs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Regulator design in my own project?
The repository has no license, so all rights stay with pravsels. Use it as a reference, and ask the author before reusing the design.
