All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (t p /GA3 10ms, /G64/GA3 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 SMD , PMAX = 20W for all other package devices IMAX = 1.0A , TJ = 25°C VO /G44 VO /G44 VO IQ /G44 IQ VN /G44 VIN /G44 VO RO Isc Ipk
