This refers to the determination of the gain frequency characteristic of the shunt regulator as an error amplifier.
Taking the configuration in figure 16, the error amplifier characteristic is as shown in figure 17.

Practical Example
Consider the example of a photocoupler, with an internal light emitting diode V = 1.05 V and I = 2.5 mA,
