Please advise on this circuit. Input is noisy 10-14.4V DC. Output goes to a 5V stepdown using a Simple Switcher IC, and to some relays and switches.
The LED is supposed to indicate if the PTC is open.
I don't have much room on the board, but I was hoping this would give some reverse-polarity protection, and protect from surges.
