5.3.1.2
To estimate the internal junction temperature, the
calculated temperature rise is added to the ambient or
offset temperature. For this example, the worst-case
junction temperature is estimated below:

From this table, you can see the difference in maximum
allowable power dissipation between the SOT-223-5
package and the SOT-23-5 package.
