The description is wrong. Maybe that's how it worked before, but now Regen actually causes it to heal (you'll see it with a green shader on the sentinel) when it has low HP. As far as I can tell, it can do it more than once per mission. It seems to cost 100 SP for it, so if the sentinel is out of SP, it won't use the skill. If it dies, it's dead until the next mission, or if you yourself die and use the revive option, it will revive with you, but that has nothing to do with the Regen mod.

What I think would be interesting, and I think I'll suggest on the forums later, is if a consumable item allows you to re-summon your Sentinel if it dies in combat.
