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 ...

In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...

The resistor and 10 uF capacitor are already forming a low-pass filter, which should prevent any spikes in either current/voltage. I don't know much about laser diodes though, so I am not sure what ...

A bunch of audio heads over at the Head-Fi forum were discussing handy and quick heat sinking methods, leading to much speculation and conjecture. This finally prompted [tangentsoft] to take matters ...

The circuit intends to produce an adjustable voltage regulator in the range of 0V to 3V with the use of the three-terminal adjustable regulator LM317. Without applying any methodology, the normal ...
