TPS629203: Output voltage accuracy

TonyMCC
Intellectual 750 points
Part Number: TPS629203

I am using the TPS629203 with FB pin VSET set to 34k (1% & 100ppm) per table 8-2 to create a 1.8V output voltage.

Can you provide a formula that calculates the output voltage accuracy relative to the VSET resistor ? 

The formula is needed so that I can calculate typical accuracy (25°C) and min/max temperature accuracy (-40°C and 85°C) when considering the VSET resistor tolerance and tempco parameters.

Thanks.
