Part Number: TL072

Hi team,

  1. Here is the circuit which achieve the -18V DC to -12V DC via TL072 and the load is about 10mA. The input and V- is connected to -18V and VDD is connected to the GND.

  2. could you help me double check the schematic to see if there is any improvement on the circuit.

Best Regards

    Hello Wesley,

    Your input is within the correct common mode range.  The output should be capable of providing that much current at that voltage.  Lastly, your supply voltages are within the data sheet spec.  I don't see anything that immediately needs to be fixed.

    If you have any concerns or other criteria, let me know and I can try to help.

    Regards,
    Daniel
