REF3440IDBVR from Texas Instruments, in a SOT-23-6. 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 | GND_F | power_in | Ground force connection. Kelvin-force ground for the reference; carries the return current from the load and should be tied to the ground plane at the load return point. |
| 2 | GND_S | input | Ground sense connection. High-impedance Kelvin-sense input that ties the internal reference amplifier's ground node directly to the remote load ground, cancelling IR drop in the GND_F return trace. |
| 3 | EN | input | Enable pin. Drive high (up to VIN) to enable the reference; drive low to place the device in shutdown. Valid range 0 V to VIN per the recommended operating conditions. |
| 4 | IN | power_in | Input supply voltage connection. Accepts VOUT + VDO up to 12 V (13 V absolute max); bypass locally with a 1 µF CIN capacitor as shown in the typical application schematic. |
| 5 | OUT_S | input | Reference voltage output sense connection. High-impedance Kelvin-sense input that lets the internal amplifier regulate the reference voltage at the remote load, cancelling IR drop in the OUT_F trace. |
| 6 | OUT_F | output | Reference voltage output force connection. Delivers the 4.096 V reference and sources/sinks up to ±10 mA into the load; decouple with a 10 µF COUT capacitor per the typical application. |
