In my circuit schematic, there is a D13 diode and an FB5 470R ferrite bead. Could you explain why a ferrite bead is used at the Vout for filtering, and why a Schottky diode isn’t included for reverse polarity or overvoltage protection? Additionally, why were these components not included in your schematic?"
You might want to ask whoever put them in your schematic. Ferrite beads help attenuate high frequency electrical noise. So help your circuits meet EMI EMC regulations. Did this particular circuit need it? Do you have a before and after scan? I frequently add beads to my schematic it looks nicer and makes people think you know what you are doing. As to the front page datasheet schematic not featuring circuits to compensated for red/black color blindness. The goal of the front page datasheet is to make the circuit look as simple and attractive as possible. Protection components that aren’t strictly necessary make that schematic look less attractive.
How likely is it that your Vin gets reversed?
