REF35409QDBVR 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 | Device ground connection. |
| 2 | GND | power_in | Device ground connection. |
| 3 | EN | input | Enable control pin; logic high (≥0.7×VIN) or floating state enables device output, logic low (≤0.3×VIN) disables device output. |
| 4 | VIN | power_in | Power supply input; operating range from VREF + VDO to 6 V maximum. |
| 5 | NR | output | Noise reduction pin; connect optional 0.1 to 10 µF low-leakage capacitor to ground for low-pass filtering. |
| 6 | VREF | power_in | Reference voltage output; 4.096 V nominal with ±0.05% maximum initial accuracy, capable of sourcing 10 mA and sinking 5 mA. |
