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 ...

The LM317 voltage regulator is well know for its versatility and ability to perform many different and varied functions. The standard and classic is the adjustable positive voltage regulator with a ...

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 ...

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 ...

LM317是应用最为广泛的电源集成电路之一，它不仅具有固定式三端稳压电路的最简单形式，又具备输出电压可调的特点。此外，还具有调压范围宽、稳压性能好、噪声低、纹波抑制比高等优点。lm317是可调节3端正电压稳压器，在输出电压范围1.2伏到37伏时能够提供 ...

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 ...
