Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection; not used internally per the SOT23-5L pin configuration. |
| 2 | NC | unconnected | No connection; not used internally per the SOT23-5L pin configuration. |
| 3 | Cathode | passive | Cathode of the shunt reference, operating from Vref to 18 V (22 V absolute max) with 100 µA to 60 mA cathode current. |
| 4 | Ref | input | Reference input connected to the external resistor divider that sets the output voltage between 1.24 V and 18 V, with typical input current of 1.5 µA. |
| 5 | Anode | power_in | Anode of the shunt reference, normally connected to ground. |
