TPS715: Internal reference accuracy

Part Number: TPS715


TPS715 reference seems 1.205V but I couldn't find the reference accuracy information.

Is the accuracy +/-4% which is Vout accuracy?

When we calculate Vout variation, it can calculate from vref and resistor divider min/max value, right?

Best regards,

  • Hi Toshihiro ,

    The accuracy specification covers all internal circuitry including the reference. Furthermore, the internal reference is the primary source of inaccuracy. As such, you can use 4% in your calculations for the reference accuracy.

    The following Application Report discusses how the resistor divider influences the overall output rail accuracy:
