1. Power dissipation
Power Dissipation Reduction (Example)
Power dissipation calculation include estimates of power dissipation characteristics and internal IC power consumption
and should be treated as guidelines. In the event that the IC is used in an environment where this power dissipation is
exceeded, the attendant rise in the junction temperature will trigger the thermal shutdown circuit, reducing the current
capacity and otherwise degrading the IC's design performance. Allow for sufficient margins so that this power dissipation
is not exceeded during IC operation.
