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 (tp ≤ 10ms , δ ≤ 5%).
5) Output voltage changes due to changes into internal temperature must be taken into account separately.
