1) All characteristics are measured with a capacitor across the input of 0.22
mF and a capacitor across the output of 0.1mF.
All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (tp £ 10ms, d£ 5%). Output
voltage changes due to changes in internal temperature must be taken into account separately.
2) Test Conditions unless otherwise stated: PMAX = 10W for TO–220SM , PMAX = 1W for Cerdip, PMAX = 20W for all other package
devices
IMAX = 1.0A , TJ = 25°C
