Hi there. I need some help with this circuit. I want to know if there is a problem with the voltage input.
You should know lm317 is an adjustable voltage regulator. That makes about 1.25V difference between adj and out pins.
Anyway, In lm317's datasheet it says maximum voltage difference : 40V
Does this mean the maximum voltage input is 40v? or what?
Because there will be a voltage drop because of led so voltage difference will be around 2-3v max.
If this circuit is problematic,Can you suggest another adjustable voltage regulator that can handle higher voltages and currents?(and cheap also )
