Notes:
1
. Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 13 W.
Power dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum
power dissipation will not be available over the full input/output voltage range.
2
. Guaranteed by design, characterization or correlation to other tested parameters.
3
. The denotes the specifications which apply over the full operating temperature range.
