Notes:

3. 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.

4. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by

the input/output differentially and the output current. Guaranteed maximum power dissipation will not be available over the

full input/output range.

5. Quiescent current is defined as the minimum output current that requires maintaining regulation. At 12V input/output

differential the device is guaranteed to regulate if the output current is greater than 10mA.

6. Vout1 and Vout2 are connected to the PCB copper area 5.5mm*5.5mm separately. If you need large PD or lower Tc & Tj,

please connect to the large copper area >> 5.5mm*5.5mm (like 10mm*10mm).
