1) Device is usable within given range without destruction, but the accuracy of the output voltage can only be

guarantied in the range specified in the line above.

2) Measured at constant junction temperature

3) Dropout voltage measured when the output voltage has dropped 100 mV from the nominal value.

4) Not subject to production test - specified by design.
