Internal error amplifier compares this pin against the internal 2.5 V bandgap; the resistor divider from CATHODE to ANODE ties here to program the regulated Vka. Reference input current range -0.05 to 10 mA (absolute max). |+| 2 | CATHODE | passive | Shunt cathode (K) - the regulated node. Sinks 1 mA to 100 mA when Vref threshold is exceeded. Vka range Vref to 36 V (abs max 37 V); continuous cathode current -100 to 150 mA. |+| 3 | ANODE | passive | Shunt anode (A), the common/ground return.
