... Additional information is needed to determine the capacitance needed to optimize phase margin or allow for process variation. A simplified model of the TL431 is shown in Figure 31. When tested for stability boundaries, the load resistance is W 150 . The model reference input consists of an input transistor and a dc emitter resistance connected to the device anode ...

... Note that the transfer function now has an extra pole formed by the load capacitance and load resistance. Note that the crossover frequency in this case is about 250 kHz, having a phase margin of about –46 degrees. Therefore, instability of this circuit is likely.
