PRODUCTION DATA
Though TLVH431 is stable with no capacitive load, the device that receives the shunt regulator's output voltage can present a capacitive load that is within the TLVH431 region of stability, shown in Figure 5-15, Figure 5-16 and Figure 5-17. Also, designers can use capacitive loads to improve the transient response or for power supply decoupling.
TI recommends to choose capacitors that give a phase margin > 5° to maintain stability of the TLVH431.
