ELECTRICAL CHARACTERISTICS
Typicals and limits appearing in normal type apply for T
J
= 25˚C. Limits appearing in Boldface type apply over the entire
junction temperature range for operation, 0˚C to 125˚C for commercial grade and −40˚C to 125˚C for industrial grade.

(1) All limits are specified by testing or statistical analysis.
(2) Typical Values represent the most likely parametric norm.
(3) Load and line regulation are measured at constant junction temperature, and are ensured up to the maximum power dissipation of 30W.
Power dissipation is determined by the input/output differential and the output current. Ensured maximum power dissipation will not be
available over the full input/output range.
