This is known as the "LMV321" or "South-East" pinout, as the output is in the lower right (south east). This pinout is common in the low voltage, "LMV" type devices (but not always!).
In Selguide, the pinput for SOT-23 & SC-70 devices is noted in the "Other Notes" section towards the bottom of the device info page. So you can do a parametric search, but make sure to verify the pinout. Unfortunately, you cannot search on pinout (yet - I am planning to add).
