Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Dropout voltage is specified over the full output current range may cause permanent damage to the device. Exposure to any Absolute of the device. Dropout voltage is defined as the minimum input/output Maximum Rating condition for extended periods may affect device differential measured at the specified output current. Test points and limits reliability and lifetime. are also shown on the Dropout Voltage curve.
Note 2:
See thermal regulation specification for changes in output voltage
Note 4:
Minimum load current is defined as the minimum output current due to heating effects. Load regulation and line regulation are measured at required to maintain regulation. a constant junction temperature by low duty cycle pulse testing.
