1) All characteristics are measured with a capacitor across the input of 0.22 F and a capacitor across the output of 0.1 F.
All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (t
p
10ms, 5%). Output
voltage changes due to changes in internal temperature must be taken into account separately.
2) Test Conditions unless otherwise stated:P
