    Hi Imran,

    Sorry for this, I have additional question.

    I downloaded PSpice model of LM2902-Q1 (automotive grade).

    I am not really sure which one is the actual spice model.
    I need a file with .txt extension to run in my simulation, I show you one example as per attached.


    Can you help me on this '.txt' file for LM2902-Q1?

    Hi Phil,

    The spice model you are looking for will be with '.LIB' extension in PSPICE model.

    Currently the released spice model is encrypted.

    Hi Imran,
    Is there a way to convert this .LIB file to .txt file?

    Thanks,
    Phil

    Hi Phil,

    You can just rename the file extension from .LIB to .txt.
    As mentioned earlier, the release spice model lib file is encrypted.
