Note 1:Output or reference voltage temperature coefficients defined as the worse case voltage change divided by the
total temperature range.
Note 2:Unless otherwise specified all limits guaranteed for TJ=25℃,Vin=Vo+1V,IL=100μA and CL=1μF.
Note 3.Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle.
Changes in output voltage due to heating effects are covered under the specification for thermal regulation.
Note 4:Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below
its nominal value measured at 1V differential. At very low values of programmed output voltage, the mini-
mum input supply voltage of 2V(2.3V over temperature) must be taken into account.
