# REF5030IDR

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

REF5030IDR 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; this pin must be left unconnected. |
| 2 | VIN | power_in | Input supply voltage; recommended range is VOUT + 0.2 V to 18 V and the absolute maximum is 18 V for REF50xxI. |
| 3 | TEMP | output | Temperature monitoring output giving about 509 mV + 2.64 mV/°C with roughly 60 kΩ source impedance, accurate to about ±15 °C, and it should be buffered when loaded. |
| 4 | GND | power_in | Ground reference pin. |
| 5 | TRIM/NR | passive | Output adjustment or noise reduction pin. |
| 6 | VOUT | power_out | Reference voltage output, sourcing or sinking up to ±10 mA with an absolute maximum of -0.3 V to 5.5 V. |
| 7 | NC | unconnected | No internal connection. |
| 8 | DNC | unconnected | Do not connect; this pin must be left unconnected. |
