i thought the LT series regulators are Linear.. I could be wrong..
Wow! If they make a lowdropout like that for 7.5 A (!?!) I need a bunch..

I have seen and messed with the LT1044 (burned one out in my Syntecno
TeeBee)
and they seem to be some sort of charge pump arrangement.. I didnt take the
time to understand this properly... Anyone ready to have a go at it?
