The power dissipation across the device is P = IOUT (VIN-VOUT). The maximum power dissipation Top ground pad Internal ground plane Printed circuit board Figure 1 is: PMAX = (TJ-TA) / (θJB +θBA ) where TJ-TA is the temperature difference between the junction and ambient air. θJB is the thermal resistance of the package, θBA is the thermal resistance through the printed circuit board, copper traces, and other materials to the surrounding air. The GND pin provides an electrical connection to ground and channeling heat away. Connect the GND pin to ground using a large pad or ground plane as a heat sink, it can improve maximize thermal dissipation. See figure 1. The SOP-8-P utilizes a bottom thermal pad to minimize the thermal resistance of the package, making the package suitable for high current applications.
