I'd recommend using an online regex generator like
https://regex101.com/.
 
This regex expression should do what you want:
[[:digit:]]{3}

Doesn't that mean _exactly_ 3 digits? (The OP wanted 1-299, which
may be one up to three digits.) Some regexp parsers allow {,3} for
an up-to range (but that might mean 0-3, thus also not the desired
expression). Or you can explicitly specify the digits range {1,3}.
