LM317: Limiting current with LM317

Part Number: LM317

Tool/software:

I have a 15V power supply. I want to limit the output current to 5mA. Would this LT317 voltaje regulator be suitable for this?

  • Hi Juan,

    I am not able to comment on LT317A, as this isn't a TI voltage regulator.

    I can, however, recommend that you consider TI's LM317 instead. Wink

    LM317DCYR can be used with R1=255Ω like the attached circuit shows, which would result in a 5mA constant current source.

    Please let me know if you have any questions!
