Hi all. I’m trying to understand how to use BA00JC5WT voltage regulator as a current regulator for drive a laser diode, just like the LM317 circuit. For the second one i found the circuit so i know how to choose the resistor…, but for the BA00JC5WT i just have the datasheet as manual, and i’m a beginner in electronic. so i’m trying to understand how to connect the 5 pin in a simple costant current regulator and how can i calcolate the resistor to get my I out. Can i just use 3 pins instead 5 pins? and is the formula the same,
Io = 1,25/R??? Please help me
take a look at this link is has a few notes that will be helpful :
