Grab a new one off a donor. Google suggests an LDO but you'll need someone with better electronics understanding.

IMHO, it's either an LDO regulator or a load switch, probably the latter. If you can confirm that it is indeed a load switch, and provided that the load side is not shorted to ground, then it should be possible to connect Vin to Vout with a jumper wire.

If Vout is shorted to ground, look for a shorted ceramic capacitor.
