    hi, i am trying to design a circuit using the cubloc devices...
    the output is suppose to be 5vdc out 20ma max.
    the relay i want to use is 24vdc 120ma coil 16a 250v contact.

    i modified a picture i found on this site. will it work?
    thanks

    It might. You do not need the 1K resistor to ground. But it will need a current limiting resistor between the 5 volt source and pin 1. Use 200 ohms.

    Yes, your new schematic is correct.
