I read the following from an article published by Microchip:
Beyond the basics, linear regulators often offer additional
features: over-current protection, thermal protection, and
reversed polarity protection to name a few.
(ww1.microchip.com/downloads/en/devicedoc/39610a.pdf)
Do you know any linear regulator with integrated "reverse polarity protection" feature in the market?
Cheers.
