Must be at least VOUT + 200 mV up to 5.5 V (absolute max 7.5 V). Bypass to GND with a low-ESR capacitor per the power-supply recommendations. |+| 2 | OUT | output | Reference output voltage (1.8 V nominal for REF3318). Sources or sinks up to ±5 mA (30 mA max). Requires a 0.1 µF to 10 µF load capacitor for stability; short-circuit current limited to ~35 mA typ. |+| 3 | GND | power_in | Device ground.
