REF5045AQDRQ1 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; do not use this pin. |
| 2 | VIN | power_in | Input supply voltage; must be at least VOUT + 0.2 V (2.7 V minimum for VOUT ≤ 2.5 V) and no more than 18 V. |
| 3 | TEMP | output | Temperature-dependent voltage output with approximately 60-kΩ source impedance, accurate to roughly ±15°C, and it must be buffered when loaded with low impedance. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM/NR | input | Trim and noise reduction pin giving a ±15-mV adjustment of VOUT; a capacitor to GND with the internal 1-kΩ resistor forms a low-pass noise filter (1 µF suggested, 14.5 Hz corner). |
| 6 | VOUT | power_out | Reference voltage output, 4.5 V for the REF5045, rated for ±10 mA output current. |
| 7 | NC | unconnected | No internal connection; do not use this pin. |
| 8 | DNC | unconnected | Do not connect; do not use this pin. |
