Figure 58. Output Voltage vs Clamp Voltage
The accuracy of this clamp is dependant on the amount of current flowing through the internal clamping diodes.
As is typical with all diodes, the voltage drop across this diode increases with current. Therefore, the accuracy
of the clamp is highly dependant upon the output voltage, the clamping voltage difference, and the output
current. The accuracy of the clamps with different load resistances are shown in Figure 59.
