NOTE1: Line Regulation and Load Regulation in Table1 are tested under constant junction temperature.
NOTE2: When load current varies between 0~2A and VIN-VOUT ranges from 1V~18V at constant junction temperature, the parameter is
satisfied the criterion in table.
NOTE3: Dropout Voltage is the voltage difference between the input and output pin when the input voltage is minimum to maintain the
lowest spec output voltage.
