REF2933AIDBZT from Texas Instruments, in a SOT-23. 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; the recommended input range is VREF + 0.05 V to 5.5 V (VREF is 3.3 V for the REF2933). |
| 2 | OUT | power_out | Reference output voltage; the recommended load current is limited to 25 mA maximum. |
| 3 | GND | power_in | Ground reference pin for the device. |
