Here's a 2.5V regulator that should work as a direct replacement on your board, for 73 cents (CDN$) each:

That one uses the same capacitors, and is good for up to 250mA of current draw. You could order a handful of those and replace the one on your board to see if it then comes back to life.

Or search Digikey for a very similar 3.3V version, using this as the search string there:

3.3V regulator SOT23-3

Then click on "PMIC - Voltage Regulators - Linear" as the category in the search results.
