7.3.2 Supercapacitor Regulation Voltage
The device allows for the supercapacitor regulation voltage, VREG, to be programmed with a resistor divider between the OUT and FB pins:
Equation 2.
Where VFB_REF is listed in the electrical characteristcs table. The resistors can be seen in Figure 7-2. The total resistance (RFBT + RFBB) should not exceed 1 MΩ.
