**Texas Instruments** · Voltage Reference · SOT-23-6

REF35120QDBVR from Texas Instruments, in a SOT-23-6. 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 | GND | power_in | Ground connection; internally shorted to pin 2 in DBV package. |
| 2 | GND | power_in | Ground connection. |
| 3 | EN | input | Enable input; logic high or floating for active mode, logic low for shutdown mode. |
| 4 | VIN | power_in | Power supply input; voltage range from VREF + VDO to 6V maximum. |
| 5 | NR | output | Noise reduction pin; connect optional capacitor to ground for output noise filtering or leave floating. |
| 6 | VREF | power_in | Precision reference voltage output with ±0.05% initial accuracy and 12ppm/°C temperature coefficient. |
