Voltage regulator in motor servo CSW V2


I just bought a non functioning CSW V2, and I try to fix it.

There was a component missing (U12) on the servo PCB, and I try to figure out what the correct component is.

I already know that it is supposed to be a voltage regulator, since there is supposed to be three of them connected in cascade, reducing the PCB input voltage from 24 -> ~12.6V -> ? -> 3.3V.

The question is what component is supposed to be in U12? A voltage regulator that regulates down to 5.0V maybe?

Note that the component currently located in U12 is not the correct one.
