REF output characteristic of the LTC1541

Category: Datasheet/Specs
Product Number: LTC1541

Hi,

About reference output voltage vs load current on page 6 of the datasheet, I have a question about sourcing current and sinking current.

Is it correct that sourcing current is the current flowing into the REF terminal and sinking current is the current flowing out of the REF terminal?

The simulation results in LTspice were the same, but let me check just to be sure.

Regards,

  • Hi  

    Yes, you are correct.

    Normally the sourcing is specified as the current going out of the part but in this datasheet, sourcing current is the current flowing into the REF terminal and sinking current is the current flowing out of the REF terminal.

    The current going out would normally have a negative deviation while the current going in will have a positive deviation; exactly what is shown in the datasheet.

    Best regards,
