REF3425QDGKRQ1 from Texas Instruments, in a VSSOP-8. 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 | ENABLE | input | Enable/disable logic input; EN ≥1.6V enables normal operation (IQ 72-95µA), EN ≤0.5V enables shutdown mode (IQ 2.5-3µA); VEN range 0V to VIN. |
| 2 | GND_S | power_in | Ground sense connection (Kelvin detection) for remote sensing of ground potential at the load location. |
| 3 | GND_F | power_in | Ground force connection (Kelvin force) establishing ground reference potential at the integrated circuit. |
| 4 | NIC | unconnected | No internal connection; test pad functional 0V to 18V; leave unconnected or tie to ground. |
| 5 | NIC | unconnected | No internal connection; test pad functional 0V to 18V; leave unconnected or tie to ground. |
| 6 | OUT_F | output | Reference voltage output force connection (Kelvin force); provides 2.5V ±0.05% at TA=25°C with output current capability ±10mA and short-circuit current limit 18-22mA. |
| 7 | OUT_S | output | Reference voltage output sense connection (Kelvin detect) for remote load voltage sensing and feedback compensation. |
| 8 | IN | power_in | Power supply input; operate from VOUT + VDO (50mV at IL=0, 500mV at IL=±10mA) minimum to 12V maximum with quiescent current 72-95µA. |
