Current-limiting regulators protect the circuits they feed but don't necessarily protect themselves against excessive dissipation. Here is an Idea For Design with a regulator that does both. A current ...

When designing the power section of any board, the most used voltage regulators are 78XX, 79XX, LM317, LM337 or similar. Engineers know these controllers are safe. reliable and easy to use, but they ...

Supplying a constant current to a variable, low-resistance load, such as a thermoelectric cooler, can be a very inefficient endeavor when using the linear approach. Even powering the linear current ...

Some projects are both educational and useful. We believe that [Jasper’s] Arduino based electronic load is one of those project. [Jasper’s] electronic load can not only act as a constant current load, ...
