Since you are using the SOT23 package, with respect to fig. 3 of the data sheet you'll have pin 1 Vcc, pin 2 Vout and pin3 GND. The component in that figure is seen from above.
I'm not sure it can works properly with no-load; it's not clear to me what the datasheet means with "output load resistance = 4.7 kohm min.": it is the minimum required load ? Or, more probably, it is able to drive load as lower as 4.7 kohm ? However you can try with a 4.7 kohm resistor between Vout and GND.
Other possibility, but I don't think it is that, you burnt the device while soldering it.
