Hi, I am having a lot of difficulty finding a driver circuit diagram suitable for my Red Laser Diode with the following specifications:
Operating Voltage= 2.4v ; Operating Current= 40mA ; Power Rating= 10mW ; Threshold Current= 24mA ; Size= TO-18 (5.6mm) ; Wavelength= 655nm. I would like to use a preferable Input Voltage= 3volts if possible. I have seen a lot of circuits and they all use a LM317 with some resistors and sometimes some capacitors, but nothing to suit the diode I have.
I need a proper circuit diagram that works, with all component values specified.
Can someone please help me with this?
