Voltage Regulator PCB
(ECE 341)
Embedded Files
This project involved designing a custom voltage regulator PCB using KiCad and the NCP1117 regulator. The board converted external DC input into a stable 5V output while incorporating protection, filtering, and power indication components. The PCB layout was designed with proper trace routing, mounting features, and manufacturable design practices, and was validated through design rule checking (DRC) before fabrication.
