Thermal Considerations

See Figure 3. The SOP-8-P is a cost-effective package

featuring a small size like a standard SOP-8 and a

bottom exposed pad to minimize the thermal resistance

of the package, being applicable to high current

applications. The exposed pad must be soldered to

the top VIN plane. The copper of the VIN plane on the

Top layer conducts heat into the PCB and air. Please

enlarge the area to reduce the case-to-ambient resistance

(θCA).
