# REF5030AQDRQ1

**Texas Instruments** · Voltage Reference · SOIC-8

REF5030AQDRQ1 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; the datasheet says do not use this pin. |
| 2 | VIN | power_in | Input supply voltage, recommended VOUT + 0.2 V minimum to 18 V maximum. |
| 3 | TEMP | output | Temperature-dependent voltage output with approximately 60-kΩ source impedance, VTEMP = 509 mV + 2.64 × T(°C), accurate to about ±15°C. |
| 4 | GND | power_in | Ground. |
| 5 | TRIM/NR | input | Trim and noise reduction pin giving ±15-mV output adjustment; a capacitor to GND (1 µF suggested) with the internal 1-kΩ resistor forms a low-pass filter. |
| 6 | VOUT | power_out | Reference voltage output (3 V for REF5030A-Q1), able to source and sink up to ±10 mA. |
| 7 | NC | unconnected | No internal connection; the datasheet says do not use this pin. |
| 8 | DNC | unconnected | Do not connect; the datasheet says do not use this pin. |
