Hi, I'm trying to do the layout for a tlv757(dbv).
I've already connected the nets with fill regions but I'm unsure which type of via I need for the pad.
The datasheet shows black dots for vias in the examples but I'm not sure exactly how big it is or how I'd derive the inner diameter when I'm only given the outer one.


 
This is my first pcb so I'd also appreciate any other improvement tips :)
