I am somewhat confused on how the current limiter configuration works with the LM317. It's configuration looks as so: Datasheet: http://www.ti.com/lit/ds/snvs774l/snvs774l.pdf The formula given is ...
I had wanted to build a power supply for so long, and had never really understood the calculations involving the LM317. I had found a kit (pcb+parts) online and it had renewed my interests in using it ...
I have a circuit where I want to have a constant current of 2mA through a variable resistor. I've been told that I could probably use a LM317 as a current regulator, with one resistor on the ouput. ...
