NOTES:
5. All regulation specifications are for a device connected as a positive-to-negative converter/regulator with R1 = 20 k
Ω, R2 = 102.5 kΩ,
external capacitor CIN = 10 μF (tantalum), external capacitor COUT = 100 μF (tantalum) and C1 = 0.002 μF (see Figure 15).
6. For voltage-loss tests, the device is connected as a voltage inverter, with terminals 1, 6, and 7 unconnected. The voltage losses
may be higher in other configurations. CIN and COUT are external capacitors.
7. Output resistance is defined as the slope of the curve (
ΔVO versus ΔIO) for output currents of 10 mA to 100 mA. This represents
the linear portion of the curve. The incremental slope of the curve is higher at currents less than 10 mA due to the characteristics
of the switch transistors.
