1) All characteristics are measured with a capacitor across the input of 2.2µF and a capacitor across the output of 1.0µF.
All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (t

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