Notes:
1 Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Power dissipation is internally limted. Regulation is guaranteed up to maximum power dissipation of 45 W. Power
dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum power
dissipation is not available over the full input/output voltage range.
2 Guaranteed by design, characterization or correlation to other tested parameters.
3 • Specification applies over the full operating temperature range.
4 IFL is defined as the minimum value of current limit as a function of input to output voltage.
