REF5020ID from Texas Instruments, in a SOIC-8. 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 must be left unconnected. |
| 2 | VIN | power_in | Input supply voltage; must be at least VOUT + 0.2 V (2.7 V minimum for REF5020) and no more than 18 V for the REF50xxI grade. |
| 3 | TEMP | output | Temperature monitoring output with VTEMP = 509 mV + 2.64 mV/°C × T and about 60 kΩ source impedance, accurate to roughly ±15 °C; buffer it with a low-drift op amp if it is loaded. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM/NR | passive | Output adjustment or noise reduction pin for the REF50xxI grade. |
| 6 | VOUT | power_out | Reference voltage output (2.048 V for REF5020); output current is limited to ±10 mA. |
| 7 | NC | unconnected | No internal connection; leave floating or connect to GND. |
| 8 | DNC | unconnected | Do not connect; this pin must be left unconnected. |
