(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, unless otherwise noted. All capacitor values
used are those recommended in Table 3. All capacitors are low-ESR Sanyo OS-CONs. The output resistance curves represent the
resistance of the device itself, which is R

in the equation for R

shown in the Capacitor Selection section.)
