REF3025AIDBZR from Texas Instruments, in a SOT-23. 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 | IN | power_in | Input supply voltage. Recommended VIN range: VOUT + 0.2V to 5.5V (absolute max 7V to GND). Optional 0.1µF input bypass capacitor. |
| 2 | OUT | output | Reference output voltage (2.5V nominal for REF3025). Load current specified up to 25mA; short-circuit current typ 35mA; stable without an output capacitor (0.1µF to 22µF supported). |
| 3 | GND | power_in | Ground reference for the input supply and output voltage. Common return for all device currents. |
