REF3230AIDBVR

Texas Instruments · Voltage Reference · SOT-23-6

REF3230AIDBVR 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 and return path to ground plane.
2 GND_S input Remote ground sense input for load-end ground monitoring; maintains maximum 200mV differential voltage with GND_F.
3 ENABLE input Digital enable/shutdown control input; ≥1.5V for active mode, ≤0.7V for shutdown (quiescent current <1µA).
4 IN power_in Positive power supply input; 3.05V to 5.5V for REF3230, requires minimum 50mV above reference output voltage.
5 OUT_S input Remote output sense input for load-end voltage feedback to enable precision remote regulation and dropout compensation.
6 OUT_F output 3.0V precision reference output for REF3230 (±0.2% accuracy, ±10mA output current, 4-7ppm/°C drift 0-125°C).
