I finally got around to build my first LM317-based voltage regulation circuit. I did a few hour of burn-in and it seem right. That's the first circuit involving an IC that I build, so I am pleased to ...

The two power supply circuits are presented to illustrate the soft start procedure using LM317 and L200 integrated circuits where each reaches the desired output of 15 V gradually for a period of 5 ...

With supply chains breaking due to the pandemic, some resources are becoming hard to procure. There are cases when someone’s profession or life, depends on these resources. Being a technical author ...

Every project needs a power supply. As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. We’ve found four different ...

Troubleshooting electrical systems often begins with a simple question: Which fuse has failed? This compact seven-channel fuse distribution board provides immediate visual feedback for every protected ...
