REF5010AIDGKR from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DNC | unconnected | Do not connect this pin. |
| 2 | VIN | power_in | Input supply voltage; for REF50xxAI it must be at least VOUT + 0.2V and no more than 18V. |
| 3 | TEMP | output | Temperature monitoring output giving VTEMP = 509mV + 2.64 × T(°C) for REF50xxAI, accurate to about ±15°C with approximately 60kΩ source impedance. |
| 4 | GND | power_in | Ground reference pin. |
| 5 | TRIM/NR | passive | Output adjustment or noise reduction pin for REF50xxAI. |
| 6 | VOUT | power_out | Reference voltage output, which sources or sinks up to ±10mA; the REF5010 output is 10.0V. |
| 7 | NC | unconnected | No internal connection; leave floating or connect to GND. |
| 8 | DNC | unconnected | Do not connect this pin. |
