REF3450IDBVR 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-sense ground return that carries the device bias/load current back to the supply return. |
| 2 | GND_S | power_in | Ground sense connection. High-impedance Kelvin-sense input used by the reference to regulate VOUT with respect to the load ground, eliminating IR drop on the GND_F trace. |
| 3 | EN | input | Enable connection. Drive high to enable the reference, low to disable it and place the device in shutdown. Must not be left floating. |
| 4 | IN | power_in | Input supply voltage connection. Operating input range up to 12V; bypass with a 1µF CIN capacitor close to the pin. |
| 5 | OUT_S | input | Reference voltage output sense connection. High-impedance Kelvin-sense feedback input; tie to the load-side of OUT_F at the point where accurate regulation is required. |
| 6 | OUT_F | power_out | Reference voltage output force connection. Delivers the regulated 5.0V (REF3450) reference with ±10mA drive; bypass with a 10µF COUT capacitor. |
