REF3030EAIDBZR from Texas Instruments, in a SOT-23-3. 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 | IN | power_in | Input supply voltage, recommended 5.75V max for REF30xxE (absolute maximum 6V) and at least VOUT + 0.2V at load. |
| 2 | OUT | power_out | Reference output voltage (3V for REF3030E), with load current of ±10mA for REF30xxE. |
| 3 | GND | power_in | Ground. |
