# REF3430MDBVTEP

**Texas Instruments** · Voltage Reference · SOT-23-6

REF3430MDBVTEP from Texas Instruments, in a SOT-23-6. 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 | GND_F | power_in | Ground force connection that carries the load return current; it may be tied to GND_S when Kelvin sensing is not used. |
| 2 | GND_S | power_in | Ground sense connection used as a high-impedance Kelvin reference point, and it may be tied to GND_F when Kelvin connections are not used. |
| 3 | ENABLE | input | Enable input: 1.6 V or higher puts the device in active mode, 0.5 V or lower puts it in shutdown with a high-impedance output, the pin must not exceed VIN, and it should not sit between 0.5 V and 1.6 V. |
| 4 | IN | power_in | Input supply voltage connection, recommended from VREF + VDO to 12 V, with an absolute maximum of 13 V. |
| 5 | OUT_S | output | Reference voltage output sense connection, a Kelvin sense point at the load that may be tied to OUT_F when Kelvin connections are not used. |
| 6 | OUT_F | output | Reference voltage output force connection, rated to source or sink up to ±10 mA of load current. |
