A search for the direct production of charginos and neutralinos in final states with three leptons and missing transverse momentum is presented. The analysis is based on 20.3 fb-1 of $$ \sqrt{s} $$ = 8TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with the Standard Model expectations and limits are set in R-parity-conserving phenomenological Minimal Supersymmetric Standard Models and in simplified supersymmetric models, significantly extending previous results. For simplified supersymmetric models of direct chargino (∼$$ \tilde{X} ^± _1 $$) and next-to-lightest neutralino ($$ \tilde{X} ^0 _2 $$) production with decays to lightest neutralino (∼$$ \tilde{X} ^0 _1 $$) via either all three generations of sleptons, staus only, gauge bosons, or Higgs bosons, $$ \tilde{X} ^± _1 $$ and $$ \tilde{X} ^0 _2 $$ masses are excluded up to 700GeV, 380GeV, 345GeV, or 148GeV respectively, for a massless $$ \tilde{X} ^0 _1 $$.
