9.2.2.2.3 Stability

Though TLVH431B-EP is stable with no capacitive load, the device that receives the shunt regulator's output voltage could present a capacitive load that is within the TLVH431B-EP region of stability, shown in Figure 20, Figure 21 and Figure 22. Also, designers may use capacitive loads to improve the transient response or for power supply decoupling.

TI recommends to choose capacitors that will give a phase margin > 5° to assure stability of the TLVH431B-EP.
