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