1) VREF = VQ – VADJ

2) Related to VQ, measured at constant junction Temperature

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

obtained at VQ = VREF.

4) Constant Junction Temperature

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

6) Minimum Output Current to maintain regulation
