Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured
at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the
package.
Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the
difference between input and output and the output current. Guaranteed maximum power dissipation will not be available over the
full input/output range.
Note 3: Output is connected to the PCB cupper area 5.5mm*5.5mm separately. If you need large PD or lower Tc & Tj, please connect to
the large cupper area >> 5.5mm*5.5mm (like 10mm*10mm).
