HARA TERISTICS
The
G
denotes specifications which apply over the full operating
temperature range.
Note 1:
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 2:
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 3:
Minimum load current is defined as the minimum output current
required to maintain regulation.
