Figure F: Plot of Equation C, used to choose the external trim resistor
value based on the desired Hold-up Capacitor charge voltage. Error
bars indicate the worst case range of charge voltage for a given exter-
nal trim resistor value (assumes 1%, 100ppm for external trim resistor
tolerance). Worst case calculation over temp range -40ºC to 125ºC.
