LM117HV/LM317HV 3-Terminal Adjustable Regulator (Rev. D)
... Although the LM317HV is stable with no output capacitors, like any feedback circuit, certain values of external capacitance can cause excessive ringing. This occurs with values between 500 pF and 5000 pF. A 1-μF solid tantalum (or 25-μF aluminum electrolytic) on the output swamps this effect and ens ...
