REF5045IDR 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 |
| 2 | VIN | power_in | Input supply voltage; minimum 4.7V (VOUT + 0.2V), maximum 18V |
| 3 | TEMP | output | Temperature monitoring pin providing temperature-dependent output voltage with approximately 60kΩ source impedance |
| 4 | GND | power_in | Ground reference |
| 5 | TRIM/NR | passive | Output adjustment or noise reduction pin for connecting external trimming resistor or noise filtering capacitor |
| 6 | VOUT | output | Reference voltage output at 4.5V nominal |
| 7 | NC | unconnected | No internal connection; leave floating or connect to ground |
| 8 | DNC | unconnected | Do not connect |
