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).
