Reverse polarity protectet 5V to 3.3 regulator

Hi, I am looking for a 5V to 3.3 regulator ( I > 15ma ) for a sensor. The Board should be as small as possible. Therefore I try to avoid a schottky diode to protect the regulator against reverse polarity. No data sheet I found so far addresses this point.
Thank you helping me Jakob

This is a forum about KiCad, and how to work with it. It is not intended as a generic electronics forum. For those there are much better websites (EEVblog, EDAboard, diyAudio, etc), and therefore I close this thread.
