PRODUCTION DATA
Though TLVH431 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 TLVH431 region of stability, shown in Figure 6-15, Figure 6-16 and Figure 6-17. 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 guarantee stability of the TLVH431.
