Hi there. I need some help with this circuit. I want to know if there is a problem with the voltage input.
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 )
