1. Line Regulation and Load Regulation in Table1 are tested under constant junction temperature.
2. When load current varies between 0~5A and Vin-Vout ranges from 1.5V~6V at constant junction
temperature, the parameter is satisfied the criterion in table. If temperature varies between
0°C≤TA≤80°C，it needs output current to be larger than 10mA to satisfy the criterion.
3. 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.
4. Minimum Load Current is defined as the minimum output current necessary to maintain regulation.
Specified output accuracy can be met when the output current exceeds the minimum load current
(10mA) and the dropout voltage (Vin-Vout) lies between 1.5V and 6V.
