All characteristics are measured with a capacitor across the input of 0.22mF and a capacitor across the output of 0.1mF. Output Voltage changes due to changes in internal temperature must be taken into account separately. Although power dissipation is internally limited, these specifications apply for up to 2W for the TO–39 package, and 1.05W for the CERDIP (J package).
