The SOT-23 device is reversed from the UA package. The SOT-23 output transistor will be turned on(drops low) in the presence of a

sufficiently strong North pole magnetic field applied to the marked face and turned off(hoists high) in the presence of a sufficiently

strong South pole magnetic field.
