NOTES: 6. Regulation specifications are for the switched-capacitor section connected as a positive to negative converter / regulator
(see Figure 105) with R1 = 23.7 kΩ, R2 = 102.2 kΩ, CIN = 10 µF (tantalum), COUT = 100 µF (tantalum), and C1 = 0.002 µF.
7. Regulation specifications are for the switched-capacitor section connected as a positive to negative converter/regulator
(see Figure 105) with R1 = 20 kΩ, R2 = 102.5 kΩ, CIN = 10 µF (tantalum), COUT = 100 µF (tantalum) and C1 = 0.002 µF.
8. For voltage-loss tests, the switched-capacitor section is connected as a voltage inverter, with VREF , OSC, and FB/SD (pins 6, 7,
and 9) unconnected. The voltage losses may be higher in other configurations.
9. Output resistance is defined as the slope of the curve (∆VO vs ∆IO) for output currents of 10 mA to 100 mA. This represents the linear
portion of the curve. The incremental slope of the curve are higher at currents less than 10 mA due to the characteristics of the switch
transistors.
