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 | VBIAS | output | Bias voltage output equal to VREF/2 (1.65 V for REF1933). Used to bias bipolar signals into the midpoint of a single-supply ADC input range. Sources and sinks up to ±20 mA. |+| 2 | GND | power_in | Device ground return. All voltages are referenced to this pin. |+| 3 | EN | input | Enable input. Device is enabled when EN ≥ VIN − 0.7 V and placed in shutdown when EN ≤ 0.7 V. Shutdown current is typically 3.3 µA. |+| 4 | VIN | power_in | Input supply voltage. Recommended operating range VREF + 0.02 V to 5.5 V; absolute maximum 6 V. Dropout is 10 mV typical at IL = 0 mA. |+| 5 | VREF | output | Reference voltage output (3.3 V for REF1933). ±0.1% initial accuracy, 25 ppm/°C max temperature coefficient. Sources and sinks up to ±20 mA; stable with 0-10 µF output capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `REF1933AIDDCR`+- `REF1933AIDDCT`++## CAD (KiCad official)++- Symbol: `REF1933AIDDCR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/ref1933aiddcr-datasheet.pdf) (32 pp, sha256 `193572512ed1817b`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
