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 ...

Hello makers in this post we’ll learn how to make LM317 based variable voltage regulator circuit module. So a obvious question come in your mind what is variable voltage regulator circuit is ? A ...

The circuit presented here can provide up to three amperes of current for a 5V, 6V, 8V, or 9V supply. It uses the popular adjustable voltage regulator LM317, which is inexpensive and is used generally ...
