# REF5020AIDGKR

**Texas Instruments** · Voltage References · VSSOP-8-0.65mm

REF5020AIDGKR 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. |
| 2 | VIN | power_in | Input supply voltage; the datasheet recommends VIN of VOUT + 0.2 V up to 18 V, with a 2.7 V minimum for the REF5020 (absolute maximum 18 V for REF50xxAI). |
| 3 | TEMP | output | Temperature monitoring output giving a temperature-dependent voltage (VTEMP = 509 mV + 2.64 mV/°C × T for REF50xxAI/I) with about 60 kΩ source impedance; low-impedance loads cause measurement error, so buffer it. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM/NR | passive | Output adjustment or noise reduction pin; the datasheet shows a 1 µF capacitor on this pin for noise reduction. |
| 6 | VOUT | output | Reference voltage output, rated for output current of -10 mA to 10 mA with an absolute maximum of 5.5 V. |
| 7 | NC | unconnected | No internal connection; the datasheet says to leave it floating or connect it to GND. |
| 8 | DNC | unconnected | Do not connect. |
