TPS7A4701-EP: Output accuracy

Part Number: TPS7A4701-EP

Hi Team, 

I have question about the output accuracy of the TPS7A4701-EP.

1. Vref accuracy

- Let me make sure the Vref accuracy. Are below correct?

Vref = 1.4V(typ)
Nominal Vref Accuracy: +/- 1% = 1.386V(min), 1.414V(max)
Overall Vref Accuracy: +/- 3.5% = 1.351V(min), 1.449V(max)
These value is guaranteed across temperature? 

2.Adjustable total Output accuracy

We can calculate total output accuracy as below. Is it correct? 

(i) Adjustable mode, 

Output accuracy = overall accuracy + Resistor accuracy + load regulation 

(ii) Any-Out mode,

Output accuracy = Overall accuracy + load regulation

  • Hi Masayuki,

    Please find my replies below.

    1. The nominal accuracy of +/- 1% is room temperature only.
    The tolerance of +/- 3.5% is across temperature.

    2.
    (i): Adjustable mode: Yes this is correct.

    (ii): Any-Out mode: Yes this is correct.

    Thanks,
