about LM317
i saw a circuit using the regulator LM317
but the strange thing about it
i saw that when there is NO input voltage to the regulator , and i inserted a voltage on the output node , i found that the input of the regulator have a voltage and not isolated is this normal issue or not
and is this condition will defect the LM317
