Extract pattern using regex

I have the following strings:

Name-AB_date, Name-XYZ_date, Name-JK_date, Name-AB_gate_date, Name-XYZ_gate_date, Name-JK_gate_date

I need a regex in PHP that will match the following substrings in each of the above strings 

AB, XYZ, JK, AB, XYZ, JK

I am currently using this the regex:

(?<=Name-)(.*)(?=_)

However in the case of

Name-AB_gate_date, Name-XYZ_gate_date and Name-JK_gate_date

It is returning 

AB_gate, XYZ_gate and JK_gate

How do I get it to just match the following in these three strings?

AB, XYZ and JK

What about this one?

Name-([^_]*)_.*

How would it be with

Name-(\w*?)_

If that fits your needs?

EDIT:

Name-(\w+?)_

If there must be more than one character.

All you need do is to make the (.*) non-greedy.

(?<=Name-)(.*?)(?=_)

.* is greedy by default. Change .* in your regex to .*?. You could try this regex also,

(?<=Name-)[^_]*(?=_)

OR

Without lookahead.

(?<=Name-)[^_]*
