All curves are generated using the test circuit of Figure 1
with V+ =5V, LV = GND, FC = open, and T
unless otherwise noted. The charge-pump frequency is
one-half the oscillator frequency. Test results are also
valid for doubler mode with GND = +5V, LV = OUT, and
OUT = 0V, unless otherwise noted; however, the input
voltage is restricted to +2.5V to +5.5V.
