    With a 20 V zener it will not operate at 13 V in.

    Hello,

    You could have a look at the LM317HV.
    This may have an input voltage of 60 Volts.
    If you want to go higher, look at the TL783.
    This may have an input voltage upto 125 Volts.

    See the datasheets for more info.

    Good point, I conveniently ignored the lower voltage limit:(
