Although Power Dissipation is internally limited, these specifications apply for Power Dissipation up to 30W for the TO–3
Package, and 20W for the TO–220 and TO–257 Packages.
3) Load and Line regulation are electrically independent and are measured using pulse techniques at low duty cycle in order to
maintain constant junction temperature. To determine the effects on the output voltage due to device heating, refer to thermal
regulation specification.
