When the VFB pin is accessible to the designer, the IBIAS term is required only in designs where the error amplifier does not operate in unity gain. The IBIAS term is located in the data sheet and is sometimes described as the adjust pin current, set pin current or the feedback pin current. In non-unity gain designs (where external resistors are used to program VOUT), we must first identify the (?VREF + ?VOS) term in (Equation 2) as discussed in Section 2.1.1. Then we must conduct a statistical analysis on Equation 2 to derive ?VE see reference [ 4].
