What kind of current are you looking to get out of it? Most opamps can only source/sink a few tens of mA, max.

Make the opamp drive a transistor instead, you need more current. That offloads the heavy lifting onto a device that can handle it (with heatsinking as necessary, of course).

Also, your regulator doesn't meet requirements. It's simply acting as an amplifier for a voltage divider. Therefore, it is unregulated. You need to use something that holds a (relatively) stable voltage drop, regardless of how much current is going through it. A bandgap reference, zener diode, or even just several regular diodes in series would do.

ALSO, come the fuck on, man. Literally the first result for "opamp voltage regulator".
