Note 1: Thermal resistance of the TO-3 package (K, KC) is typically 4˚C/W junction to case and 35˚C/W case to ambient. 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 µF, and a capacitor across the output of 0.1µF. All characteristics except noise voltage
and ripple rejection ratio are measured using pulse techniques (t ≤ 10 ms, duty cycle ≤ 5%). Output voltage changes due to changes in internal temperature must
w
be taken into account separately.
Note 3: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. For guaranteed specifications and the test conditions, see Elec-
trical Characteristics.
