Application Information (Cont.)
Thermal Consideration
See Figure 3. The SOP-8P 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 V
Top layer conducts heat into the PCB and air. Please
enlarge the area to reduce the case-to-ambient resistance
