LT1118 Resistors selection for 3.3 output voltage

Category: Hardware
Product Number: LT1118

Hello,

We have an LT1118CS8#PBF adjustable voltage regulator. The problem I confront is picking the correct resistor values for 3.3v output and 800mA as I have no clue what is the VFB and.

VOUT = VFB *(1 + R1/R2) + IFB*R1

What are the Feedback voltage and current? Is it fixed or needed to be calculated? The datasheet doesn't tell anything about it.
