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

a constant junction temperature by low duty cycle pulse testing.

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.
