TPS71501-EP: Vout Accuracy

David Calarco

Part Number: TPS71501-EP

I am using this part number with an adjustable output using external resistors. Is the Vout accuracy of 6.25% based on using a fixed votlage output? Or if not, what is the source of the accuracy on Vout?

Hey David,

The Vout accuracy is for a fixed voltage output.
Thus if I set the output to 5 V, I would expect the output to be 5 V +/- 6.25%

Thanks,
Daniel

I do not quite follow the answer. The part is available in both fixed and adjustable output versions. The datasheet is not clear which of those the +/-6.25% applies.

So, if I use a fixed output version is the tolerance +/- 6.25%?

If I use the adjustable version is the tolerance now equal to +/- 6.25% PLUS the tolerance of the external set point resistors?

Thanks

Hey John,

You are correct in stating the tolerance is +/- 6.25% PLUS the tolerance of the external resistors.

Thanks,
Daniel
