is P = IOUT (VIN-VOUT). The maximum power dissipation
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. The thermal pad is soldered to the top
ground pad and is connected to the internal or bottom
ground plane by several vias. The printed circuit board
(PCB) forms a heat sink and dissipates most of the
