Bench and system power supply
M9OMS VLDO V2 — very low dropout (LDO) linear voltage regulator for QRP. Quiet 9/12/13.8 V, 2 A, for QRP radios. No switching noise.
Precision 0–50 V programmable laboratory PSU with 1 mV/1 mA setting steps, hybrid synchronous-buck + linear regulation, STM32G474 control, INA228 metering, and layered hardware protection.
This repository contains the design files for a reliable and safe 12V DC Regulated Power Supply. The circuit is designed to convert an AC input (from a transformer) into a stable 12V DC output, focusing on high-voltage safety, heat management, and low-ripple performance.
Understanding how a transformer, bridge rectifier, filter capacitor and LM7805 work together to produce a stable 5V output through LTspice simulation and practical implementation.
Designing a negative linear voltage regulator with discrete components. This project was followed by a physical implementation.
1.0 V capless PMOS LDO in 90 nm CMOS — hand-derived sizing, PVT + Monte Carlo verification, DRC/LVS-clean layout
PCB design project using KiCad 9: single-sided 5V regulated power supply with LM7805, full design workflow from schematic to Gerber files.
The module can be fitted in housings linear stabilizers D2PAK (TO263), SOT223, DPAK (252).
Boardoza SPX1117 ADJ Breakout Board is an adjustable low-dropout linear regulator board with selectable 5V, 3.3V, and 1.8V outputs.
Convert AC input to stable 12V DC with this reliable power supply design featuring high-voltage isolation and thermal management for industrial safety.
