REF3212AIDBVR 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 reference connection providing the 0V bias point for the internal circuitry. |
| 2 | GND_S | input | Remote load-end ground sensing input; differential voltage from GND_F must remain ≤200mV to prevent ESD diode conduction. |
| 3 | ENABLE | input | Digital enable/disable control input; device enters shutdown mode at ENABLE<0.7V, operates normally at ENABLE>1.5V. |
| 4 | IN | power_in | Positive power supply input; operating range from VOUT+50mV (minimum 1.8V for REF3212) to 5.5V, absolute maximum rating 7.5V. |
| 5 | OUT_S | input | Remote load-end voltage sensing input for 4-wire Kelvin measurement; enables device compensation for PCB trace voltage drops. |
| 6 | OUT_F | output | Reference voltage output; sources ±10mA output current with nominal 1.25V for REF3212 and 50mV minimum dropout voltage. |
