Way back, Silicon gave this advice ...

Reverse biased power diodes across the output terminals and the pass transistor are usually recommended.

This will offer protection from a capacitor in the load trying to discharge into the PSU when you turn off. This would cause the output MOSFET get reverse biased. I guess the 'reverse' diode across the output is there to protect from reverse charged (film) cap when you connect up
