The LM317 adjustable voltage regulator is used in this project to produce a power supply that can be used for testing and debugging purposes. The voltage regulator contains 1N4001 protection diodes in ...

This simple LM317 (three terminal voltage regulator) power supply is giving an adjustable voltage output of 1.25V to 25V and capable of delivering 1.5A. You can adjust the output voltage by turning ...

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 ...

It couldn’t be simpler but you have to admit that a small adjustable portable power supply like this one will be really handy. The main part of the PSU is an LM317 linear voltage regulator which we’re ...
