We investigate superconducting pairing driven by electron-electron interactions in a theoretical model for monolayer MoS2 with the temperature-flow functional renormalization group(fRG). At low doping, the dominant instability is toward odd-parity pairing with f-wave Mo-nearest-neighbor structure. We compute the fRG phase diagram versus electron doping below the van Hove filling of the conduction band. In the superconducting regime, the critical temperature grows with doping, comparable to the experiments. Near van Hove filling the system favors a ferromagnetic state. We demonstrate that the triplet pairing is driven by ferromagnetic fluctuations and that the multiorbital nature of the conduction band as well as the Hund's coupling appear crucial in making the physics of MoS2 different from e.g. doped graphene.
