1) All characteristics are measured with a capacitor across the input of 0.22µF and a capacitor across the output of 0.1µF.
All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (tp ≤ 10ms, δ ≤ 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 , P MAX = 1W for Cerdip, P MAX = 20W for all other package
devices
IMAX = 1.0A , TJ = 25°C
