REF2030QDDCRQ1 from Texas Instruments, in a SOT-23-5. 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 | VBIAS | output | Bias voltage output (VREF/2) that tracks VREF to 7 ppm/°C maximum over -40°C to 125°C, with ±20 mA load current and 50 mA short-circuit current limit. |
| 2 | GND | power_in | Ground pin, the device reference for the supply and outputs. |
| 3 | EN | input | Enable input: the device operates when EN ≥ VIN - 0.7 V, and when pulled low (0 to 0.7 V) it enters low-power shutdown with outputs high-impedance and quiescent current reduced to 5 µA; absolute maximum range is -0.3 V to VIN + 0.3 V. |
| 4 | VIN | power_in | Input supply voltage with a recommended range of VREF + 0.02 V to 5.5 V and an absolute maximum of 6 V. |
| 5 | VREF | power_in | Reference voltage output (VREF), 3.0 V for the REF2030 variant, with ±0.05% maximum initial accuracy, 8 ppm/°C maximum drift over -40°C to 125°C, and ±20 mA load current. |
