    Just for the record, I ran into the same situation recently. I end up tying the backlight to 12V. Works well and keeps the 7805 nice a cool.

    Hi
    i saw another application where 47E is used instead of 11E in series to backlit LEDs circuit
    However perhaps it is better Rytech cold analyze the current breakup-- may be the current is draining thro another circuit path
