REF5050IDR 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; pin is not internally connected and is reserved for future functionality. |
| 2 | VIN | power_in | Supply voltage input accepting voltage from VOUT + 0.2V to 18V maximum at specified load conditions. |
| 3 | TEMP | output | Temperature monitoring output providing voltage proportional to die temperature at 2.64 mV/°C sensitivity over -40°C to 125°C range with approximately 60kΩ source impedance. |
| 4 | GND | power_in | Ground reference and return path for supply and output load currents. |
| 5 | TRIM/NR | passive | Trim and noise reduction pin allowing ±15mV adjustment of VOUT or passive RC filtering when capacitor is connected between pin and GND. |
| 6 | VOUT | output | Reference voltage output of 5.0V nominal with ±10mA output current capability and 1μF to 50μF load capacitance range. |
| 7 | NC | unconnected | No internal connection; pin is not used in this device variant. |
| 8 | DNC | unconnected | Do not connect; pin is not internally connected and is reserved for package compatibility. |
