The third pin——is what separates this IC from the pack. The datasheet reveals that the regulator maintains a constant 1.25V reference between the Output and Adjust pins. This clever architecture means the "ground" reference for the chip isn't actually Earth ground; it "floats" relative Primary Applications | Parameter | Test Condition |
