REF3225AIDBVT 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 | Device ground connection; GND_F and GND_S differential voltage must not exceed 200mV to prevent ESD protection diode conduction. |
| 2 | GND_S | input | Load end ground remote sensing input; connects to load ground junction with maximum 200mV differential vs GND_F for Kelvin sensing. |
| 3 | ENABLE | input | Digital enable/disable input; output disabled when voltage is below 0.7V, enabled when voltage exceeds 1.5V. |
| 4 | IN | power_in | Positive power supply input; operating range from VOUT + 50mV (minimum 2.55V for REF3225) to 5.5V. |
| 5 | OUT_S | input | Remote output sensing input; connects to load output junction for Kelvin feedback regulation to compensate for trace resistance. |
| 6 | OUT_F | output | Reference voltage output; nominal 2.5V (2.495V to 2.505V typical range) with ±10mA sourcing/sinking capability when VIN ≥ VOUT + 250mV. |
