The LT3080 is a low dropout linear regulator. I will be using the big brother (the LT3081) in an upcoming project (Stay tuned for the LT3081 Eagle file and the project as well :D). I like this regulator as it is capable of true 0V output and has good noise performance.

Datasheet is here:

As always, Let me know if there is anything you good people want to see.
