TPS7A49: datasheet possible error.

Part Number: TPS7A49

Looking through the datasheet for the TPS7A49 and looking at the typical application example.  Specifically page 17.  Equation 5 calculation of R1.  The calculations comes out to 1.265K.  However, the next line says to select R1 at a value of 68.1K.

Is this an error in the datasheet?

    Hi Greg, 

    Thanks for the feedback. You are correct, the values of R1 should be 1.25K Ohms not 68.1 KOhms. The 68.1KOhms will generate a 2V output instead of 1.2V. This error will be fixed next time when we release a new revision of the datasheet. 

    Regards,
