## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect pin reserved for manufacturing purposes; users should not connect anything to this pin. |
| 2 | VIN | power_in | Supply input; the datasheet specifies a 6.0 V to 15 V supply range with an 18 V absolute maximum supply voltage. |
| 3 | NC | unconnected | No connect pin reserved for manufacturing purposes; users should not connect anything to this pin. |
| 4 | GND | power_in | Ground reference; a bypass capacitor is connected from VOUT to this GND pin in the basic reference configuration. |
| 5 | NC | unconnected | No connect pin reserved for manufacturing purposes; users should not connect anything to this pin. |
| 6 | VOUT | power_out | Reference output delivering 5.000 V nominal with a guaranteed load current of up to 5 mA. |
| 7 | NC | unconnected | No connect pin reserved for manufacturing purposes; users should not connect anything to this pin. |
| 8 | NC | unconnected | No connect pin reserved for manufacturing purposes; users should not connect anything to this pin. |
