Dual output adjustable power supply based off of the SIC431 chip for high current output in a very small form factor and end-user choice of linear side regulator for low ripple output or standby power.
Applications: Robotics. Portable and wearable electronics. Low or high power applications. Battery powered electronics. Custom built small compute devices.
Features: Dual output, switching and linear. SIC431 based switching side. End-user choice of linear regulator. Tuneable or programmable switching side voltage output via potentiometer or bypass jumper. Daisy-chain or fully separate supply to linear regulator configured by solderable jumpers. Enable/Disable pin for switching side with optional pull up/down resistor pads. VReady pin from switching side for sensitive electronics.
Warning: Higher Amperage draw will cause the board to reach temperatures not suitable for direct skin contact. An enclosure to prevent direct contact and a heatsink with sufficient cooling air should be used to reduce working temperature.

Questions
How big is the Gauntl33tVoltageRegulator PCB?
It measures 35 × 25 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Gauntl33tVoltageRegulator use?
32 parts, built around the L7805 and EMK316BBJ476ML-T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Gauntl33tVoltageRegulator KiCad files?
From the Haptic-Solutions/MicroPSU repository on GitHub, at the commit this page was made from: the board is Gauntl33tVoltageRegulator.kicad_pcb and its schematic Gauntl33tVoltageRegulator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gauntl33tVoltageRegulator design in my own project?
Its repository states no licence, so its author keeps all rights: ask Haptic-Solutions before reusing the design.
