LM117HVQML-SP: Current rating for LM117H MDE die version

David Ben Chamo
Prodigy 85 points
Part Number: LM117HVQML-SP

Hello

My question is regarding the die version of the part: LM117H MDE (not for the packaged part)

Can you please advise what is the max. current at Tj=105C

At the following setup:

Vin = 10.3V, Vout = 8V

and please specify the MTBF at the same conditions with output current = 500mA

Thanks

    Hello David,

    Your maximum current limit will have a relationship to temperature and the device heatsink/mounting. Therefore I am unable to say as it depends how you integrate the die.

    The MTBF information can be found at www.ti.com/.../estimator.tsp. Please let me know if you have further questions.

    Thanks,
    Kyle

    Hi David,

    To clarify, your current limit is actually going to be above 500mA. However, you may hit the thermal limit depending on heatsink/mounting of the die. The thermal shutdown at a high temp will look like a current limit though.

    Thanks,
    Kyle
