LM78LXX Series
LM78LXX Electrical Characteristics
Limits in standard typeface are for T
J
= 25˚C,
Bold typeface
applies over 0˚C to 125˚C for SO-8 and TO-92 packages, and −40˚C to 85˚C for micro SMD package.
Limits are
guaranteed by production testing or correlation techniques using standard Statistical Quality Control (SQC) methods. Unless
otherwise specified: I
