Thermal resistance of the TO-220 package (T) is typically 4§C/W junction to case and 50§C/W case to ambient. Note 2: All characteristics are measured with capacitor across the input of 0.22 mF, and a capacitor across the output of 0.1mF. All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (tw s 10 ms, duty cycle s 5%). Output voltage changes due to changes in internal temperature must be taken into account separately. 2
