http://www.semelab.co.uk1) All characteristics are measured with a capacitor across the input of 0.22
μ
F and a capacitor across the output of 0.1
μ
F.
All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (t
p
≤
10ms,
δ ≤
5%). Output
voltage changes due to changes in internal temperature must be taken into account separately.
