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 GUID-205FC173-8D8B-4ABC-B7D7-7A8E2D0DA261.html#SLVS555GRAPH3280, GUID-205FC173-8D8B-4ABC-B7D7-7A8E2D0DA261.html#SLVS555GRAPH9577 and GUID-205FC173-8D8B-4ABC-B7D7-7A8E2D0DA261.html#SLVS555GRAPH8785. 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.
