8.1.1 Adjustable Device Feedback Resistors

The adjustable-version device requires external feedback divider resistors to set the output voltage. VOUT is set using the feedback divider resistors, R1 and R2, according to the following equation:

Equation 2. VOUT = VFB × (1 + R1 / R2)

To ignore the FB pin current error term in the VOUT equation, set the feedback divider current to 100x the FB pin current listed in the Electrical Characteristics table. This setting provides the maximum feedback divider series resistance, as shown in the following equation:

Equation 3. R1 + R2 ≤ VOUT / (IFB × 100)
