____________________________Typical Operating Characteristics (continued)
(All curves generated using the inverter circuit shown in the Typical Operating Circuits with LV = GND and T A = +25°C, unless other-
wise noted. Test results also valid for doubler mode with LV = OUT and T A = +25°C. All capacitor values used are those recom-
mended in Table 3, unless otherwise noted. The output resistance curves represent the resistance of the device itself, which is R O in
the equation for R OUT shown in the Capacitor Selection section.)
