Hi Team,

Please help to confirm the thermal data of LMV331IDBVRG4, which is not list on data sheet.

Thanks

    Hello Daniel,

    I will put in a request for the thermal information. The stated response time is up to two weeks, but usually it takes a day or two.

    Hello Daniel,

    FYI: It looks like the LMV331IDBVRG4 will soon be obsolete.

    The "G4" suffix denotes a "green" (non-Pb) package back from when the packages still contained lead.

    Current devices have been converted to "green" packaging, so you do not need to order the "G4" version. The "G4" versions are obsoleted as the packages are converted.

    So you should order the LMV331IDBVR instead, which is essentially the same device (same die, same package).

    Hello Daniel,

    The results are in:

    Device Name:

    LMV331IDBVR

    Result- Theta JA-High K (standard datasheet value):

    232.8

    Result-Theta JC, top (standard datasheet value):

    149.4

    Result-Theta JB (standard datasheet value):

    89.7

    Result- Psi JT (standard datasheet value):

    61.5

    Result- Psi JB (standard datasheet value):

    89.2

    Result-Theta JC, bottom (standard datasheet value):

    n/a

    Note: These new numbers are based on thermal modeling and should be more accurate than the old template-based numbers currently in the datasheet.
