REF3133AIDBZR from Texas Instruments, in a SOT-23-3. 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. Operates from V_REF + 0.05 V up to 5.5 V (absolute max V+ to V- = 7 V). Typical quiescent current 100 µA. |
| 2 | OUT | output | Reference output voltage (3.3 V nominal, 3.2934 V to 3.3066 V at 25°C). Can source or sink up to 10 mA. Stable with any capacitive load; no external output capacitor required. |
| 3 | GND | power_in | Ground reference for the device. |
