TPS7A11: Design Review Request

TPS7A11: design simulation

Ben Kuo
Expert 7295 points
Part Number: TPS7A11

Dear team,

Customer want to use TPS7A11 for 1.1Vin to 0.75Vout/0.11A, and Vpp need to within 1% spec(constant load).

Did we have simulation or calculation can verified device performance?

Regards,

Ben

    Hi Ben,

    Please review your bias voltage.  You will need some bias voltage headroom at 110mA of load.

    I see the requirements are DC only.  Depending on your package and min/max junction temperature (and assuming Vbias is not in dropout), this may be able to be met.  The EC table has worst case tolerances across line, load and temperature but your requirements are likely inside of these.  So I would use the typical datasheet curves.

    Thanks,

    Stephen
