DIY Breadboard Power Supply

Показать описание

I decided to make my own breadboard power supply because I wasn't happy with any of the other options on the market. I wanted adjustable voltage, a voltage display, and safety features -- all at an affordable price.

So I partnered with JLCPCB to design and make this DIY power supply for breadboard use. It is based around the TLV767 chip and has output voltage ranging from 0.8 to 14 volts. Not bad!

Unfortunately, it may overheat under certain conditions, meaning that my PCB design does not provide enough surface area for cooling. Still, it is a good first attempt, in my opinion. It can provide 1W without issues, which is enough for many basic projects.

why not add some screws beside the chip and then screw on a heatsink? or maybe you can make it so that the chip controls the output voltage using a mosfet, which should also be able to solve the problem

you have a lot of space for a 2mm chip... it's nonsense!
you can use bigger voltage regulator!
tiny chips are for tiny projects and... tiny currents 😊

Disappointed. Why go through all the trouble, and it still requires a barrel jack. Make it use usb C PD atleast 😉
