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

REF4132B30DBVRQ1 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 that should be left floating. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | EN | input | Enable pin that enables or disables the device, with enable voltage limited to 0 V to VIN per the recommended operating conditions (absolute maximum VIN + 0.3 V). |
| 4 | VIN | power_in | Input supply pin; recommended input voltage is VREF + VDO to 5.5 V, with an absolute maximum of 6 V. |
| 5 | VREF | power_out | Voltage reference output with output current rated ±10 mA, 20 mA maximum short-circuit current, and an absolute maximum voltage of -0.3 V to 5.5 V. |
