# REF5010IDGKR

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

REF5010IDGKR from Texas Instruments, in a VSSOP-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; this pin must be left unconnected. |
| 2 | VIN | power_in | Input supply voltage; recommended range is VOUT + 0.2V to 18V and the absolute maximum is 18V for the REF50xxI. |
| 3 | TEMP | output | Temperature-monitoring output with VTEMP = 509mV + 2.64mV/°C × T and about 60kΩ source impedance, so low-impedance loads cause measurement error and should be buffered. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | TRIM/NR | passive | Output adjustment or noise-reduction pin; the datasheet gives no separate numeric limit for this pin on the REF50xxI variant. |
| 6 | VOUT | power_out | Reference voltage output, rated for an output current of ±10mA with an absolute maximum output voltage of -0.3V to 5.5V. |
| 7 | NC | unconnected | No internal connection. |
| 8 | DNC | unconnected | Do not connect; this pin must be left unconnected. |
