_MAX= 25W for T–Pack (TO–220) Package.

_MAX= 15W for SG–Pack (TO–220SM) Package.

3) All characteristics are measured with a capacitor across the input of 0.22µF and a capacitor across the output of 0.1µF.

4) All characteristics except noise voltage and ripple rejection ratios are measured using pulse techniques (t_p≤ 10ms , δ ≤ 5%).

5) Output voltage changes due to changes into internal temperature must be taken into account separately.
