Internally tied to the negative rail of the voltage reference and pass-transistor return. |+| 2 | VOUT | power_out | Regulated 3.3V output. Requires an output capacitor of 1uF tantalum or 6.8uF ceramic for stability. Delivers >400mA output current when Vin-Vout >= 1V. |+| 3 | VIN | power_in | Unregulated input supply, 3.5V to 15V (absolute max 18V).
