REF5050IDGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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 - has no internal connection and should not be externally connected. |
| 2 | VIN | power_in | Supply voltage input accepting VOUT + 0.2V to 18V with maximum quiescent current of 1.2mA (-40°C to 125°C). |
| 3 | TEMP | output | Temperature sensor output providing 575mV nominal at 25°C with 2.64mV/°C sensitivity and high source impedance for monitoring die temperature. |
| 4 | GND | power_in | Reference ground providing return path for circuit currents up to ±10mA. |
| 5 | TRIM/NR | passive | Trim/noise reduction node with high output impedance for connection to external capacitors for filtering or resistor networks for ±15mV output adjustment. |
| 6 | VOUT | power_out | Precision 5.0V reference voltage output sourcing or sinking ±10mA with ±0.05% initial accuracy and 3ppm/°C temperature coefficient. |
| 7 | NC | unconnected | No internal connection - may be left floating or connected to ground without affecting circuit operation. |
| 8 | DNC | unconnected | Do Not Connect - has no internal connection and should not be externally connected. |
