REF2925AIDBZT 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; VIN must be at least VREF + 0.05 V and no more than 5.5 V per the recommended operating conditions. |
| 2 | OUT | output | Reference output voltage, which is 2.5 V for the REF2925 per the device comparison table; the device does not require a load capacitor but is stable with any capacitive load. |
| 3 | GND | power_in | Ground reference pin. |
