  • why you put a voltage regulator??? it can work @15V with no problem! I use this IC @ 15V and i didn't burned anything!

  • if i didn't use 7809, then the leds are fail. (at 12V)

  • @Gecman

    banolu is right, 3915 is an led driver so it regules voltage for leds. it can work safely with 12v and leds'll be fine.

  • HI! the voltage regulator (9volt) is not required. the lm3915 can work at 12 volt. just like a comment ok? have a good day!
