ldo interview

Hi Folks
I am gonna have a onsite interview about LDO and DC-DC converter. I need some suggestions or even some interview questions about these . I know the guy will interview me is trick tester and he likes to give some tricky questions about power conversion and I just start to learn power electronics this semester and don't have an deep understanding so I am so worried about this.
I am eagerly looking forward to the suggestions or interview question from you guys!!!

ldo interview questions

Dear cqdevil :
I think you really need to do some homework :
1.Some performance definitions.
(eg: line regulation / load regulation)
2.LDO loop transfer function.
3.How to compensate LDO ?

I hope these will help you.

Good Luck.
I hope you have a good news.
