I am using ST1s12G12R. I could not find the datasheet for it. The datasheet available is for ST1S12-ADJ. I would like to know how should I connect FB pin and if possible please provide sample circuit to use ST1S12G12R to generate 1.2V

Welcome, @VUV.2, to the community!
The data sheet, which you can find on the product website, also contains the ST1S12G12R. The typical application circuit is actually only shown for the ADJ variant.
However, the general consensus is that with the ST1S12G12R you leave out the resistors and connect pin VFB directly to the output voltage because the resistors are already present internally. So all you need for a complete 1.2V regulator is the ST1S12G12R, two capacitors and the coil.
Does it answer your question?
