Layout Considerations

The primary path for heat conduction out of the SC-70

or SOT-23 package is through the package leads.

Using heavy wide traces at the pads of the device will

facilitate the removal of the heat within the package,

thus lowering the thermal resistance R

θJA. By lowering

the thermal resistance, the maximum internal power

dissipation capability of the package is increased.
