REF3312AIDBZR from Tokmas REF3312AIDBZR TOKMAS, 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 | VIN | power_in | Power supply voltage input. Operating range 2.7 V to 5.5 V (must be at least VOUT + 0.2 V dropout). A 1 µF low-ESR ceramic bypass capacitor is recommended close to this pin. |
| 2 | REF | output | Reference voltage output. Provides 1.25 V nominal with ±0.1% initial accuracy and 20 ppm/°C max tempco. An external 0.1 µF to 10 µF ceramic capacitor is required for stability; sources/sinks up to ±5 mA. |
| 3 | GND | power_in | Device ground reference. |
