REF5050AQDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DNC | unconnected | Do not connect; do not use. |
| 2 | VIN | power_in | Input supply voltage, requiring VOUT + 0.2 V (or 2.7 V minimum for VOUT ≤ 2.5 V) up to 18 V. |
| 3 | TEMP | output | Temperature-dependent voltage output with approximately 60-kΩ source impedance, following VTEMP = 509 mV + 2.64 mV/°C × T. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM/NR | input | Trim and noise reduction pin providing ±15-mV adjustment of the device bandgap (and hence VOUT); a capacitor to GND with the internal 1-kΩ resistor forms a noise-reduction low-pass filter. |
| 6 | VOUT | output | Regulated reference voltage output, capable of sourcing/sinking up to ±10 mA. |
| 7 | NC | unconnected | No internal connection; do not use. |
| 8 | DNC | unconnected | Do not connect; do not use. |
