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
