For example, see this page for buying a LTC3388 step-down regulator, and note the difference between the LTC3388EMSE-1#PBF and LTC3388IMSE-1#PBF.
What's the difference? Is this notation specific just to components from Linear Technology? Why is one more expensive than the other?
I've tried to Google this a number of times with no luck.
Edit: I've also seen EDD vs. IDD. What does the 'E' and 'I' stand for in all of these acronyms?
(It'd be helpful to know what the rest of the letters stand for too)

have the specifications guaranteed over the full range (possibly meaning binning).
