**Texas Instruments** · Voltage Reference · SOT-23-5

REF4132B30DBVR from Texas Instruments, in a SOT-23-5. 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 | N/C | unconnected | No connect pin, leave floating. |
| 2 | GND | power_in | Ground connection. |
| 3 | EN | input | Enable control input to enable or disable the reference output. |
| 4 | VIN | power_in | Supply voltage input for the reference circuit, minimum (VREF + VDO) to maximum 5.5 V at recommended operating conditions, 6 V absolute maximum. |
| 5 | VREF | power_in | Reference voltage output, 3.0 V nominal at ±0.05% initial accuracy, ±10 mA output current capability. |
