1) All characteristics are measured with a capacitor across the input of 0.22mF 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 SMD , PMAX = 20W for all other package devices
IMAX = 1.0A , TJ = 25°C
