PCB layout suggestion
Thermal considerations
The lead frame die pad, of ST1S10, is exposed at the bottom of the package and must be
soldered directly to a properly designed thermal pad on the PCB, the addition of thermal
vias from the thermal pad to an internal ground plane will help increase power dissipation.
