Line Regulation

Note 1

Thermal resistance of the TO-3 package (K KC) is typically 4 CW junction to case and 35 CW case to ambient Thermal resistance of the TO-220

package (T) is typically 4 CW junction to case and 50 CW case to ambient

Note 2

All characteristics are measured with capacitor across the input of 022 mF and a capacitor across the output of 01mF 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
