TLV702-Q1: Difference between TLV70225DSER and TLV70225QDSERQ1

Part Number: TLV702-Q1
Other Parts Discussed in Thread: TLV702,

Hello team,

I received a inquiry from my customer about the spec difference between TLV702 and TLV702-Q1.

Are their any spec difference between these catalog and Q1 products?

In the data sheet, the shutdown current was different as the following values:

　TLV70225QDSERQ1：2.5uA(max)
　TLV70225DSER：2uA(max)

I assumed that this is a difference due to the test conditions where Q-1 was tested at 125°C and catalog was at 85°C. If Q-1 is also at 85°C, it will be the same specification as catalog. Please let me know if my assume was wrong.

If there are any differences other than that of the AEC-Q100 test conditions, please let me know.

Best Regards,

Ryotaro Fukui

    Hello Ryotaro,

    You are correct about the shutdown current. The TLV702Q1 also is available with an additional package. It is available with the DDC package, which changes the whole thermal resistance of the product if you decide to use that package. Please let me know if you have any other questions.

    Thank you,

    Hello Josh,

    Thank you for the prompt response.

    So the difference on the data sheet was due to the difference in the test environment.

    Just to be sure, was the test condition in Q1 different because it was the AEC-Q100 test? Can I think of the device as exactly the same, except for the test conditions? Since it is a replacement inquiry, I would like you to tell me if there are any differences.

    Thanks,

    Hi Ryotaro,

    Yes, I think it is safe to say that the reason that the shutdown current is slightly less is because of the 40 degree difference in the junction temperature when running the tests. Also, you should be fine using this as a replacement.

    Thank you,

    Hello Josh,

    Thank you for checking. Since it was appropriate as a replacement device, I have recommended it to the customer once again.

    They seems to be satisfied, so I would like to declare this case closed. Thank you for your help.

    Thanks,
