Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Cathode | passive | Cathode is the shunt current path of the reference, rated at a maximum cathode-anode voltage of 37 V (36 V recommended operating) and a cathode current of 1 mA to 100 mA in regulation, with an absolute maximum of 150 mA. |
| 2 | Ref | input | Ref is the reference input that sets the output voltage through an external divider, with a reference voltage of about 2.495 V and a reference input current of 2 µA typical (4 µA max), and an absolute maximum reference input current of 10 mA. |
| 3 | Anode | passive | Anode is the common terminal of the shunt reference; the datasheet states no separate electrical limit for this pin beyond the cathode-anode ratings. |
