Part Number: TPS7A85A
Other Parts Discussed in Thread: TPS7A85,

Dear Team,

Can you please summarize in a short table the differences between the TPS7A85 and the TPS7A85A

Best Regards,

Nir

  • Thanks Prakash,

    Are there any additional features we've implemented/corrected on the TPS7A85A ?

    Regards,

    Nir.

  • Nir,

    Yes - TPS7A85A improvements are as below:

    1.p2p to and with same functionality/specs as TPS7A83/4/5

    2.Better Noise (4uVRMS)

    –incremental improvement vs. TPS7A85

    3.Startup with negative voltage

    –simplified multi-rail sequencing

    4.No sequencing requirement between VIN, VBIAS and EN

    5.Reverse current rating

    Regards,
