HARA TERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
to the device may be imparied.
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.
