There are basically two questions I have for this circuit.
1) Which capacitor configuration is good? before fuse or after fuse
2) How do I limit my inrush current?
My thoughts: I am confused between weather to put filtering capacitor before the fuse or after the fuse? Putting a capacitor at the IN (Voltage in) pin of the voltage regulator(LM1085) is recommended by LTC. According to me, if I put my cap after the fuse, it will act like a short when I connect my 12V PC supply to my board. The inrush current could kill my fuse every-time I connect PC-supply. To me putting a cap before the fuse make sense but still, I have a feeling it could still act like a short during inrush and harm my PC-supply. What I want is a nice filtering at the IN pin of my regulator while limiting my inrush current. The circuit powered by my regulator (U2) has max 300 mA loading. Any suggestion of what I need to do here?
