    Hi,

    Does any one know how to connect two units of LM338 in series in order to double the voltage?

    TQ.

    This is a text part of its datasheet

    Since
    the regulator is “floating” and sees only the input-to-output
    differential voltage, supplies of several hundred volts can be
    regulated as long as the maximum input to output differential
    is not exceeded, i.e., do not short-circuit output to ground.

    Thus you only have to double the input voltage and take care of the above situation. Thus you only needs one Lm338
