LM78LXX Electrical Characteristics
Limits in standard typeface are for T
J
= 25C,
Bold typeface ap-
plies over 0C to 125C for SO-8 package and 40C to 85C for micro SMD package.
Limits are guaranteed by produc-
tion testing or correlation techniques using standard Statistical Quality Control (SQC) methods. Unless otherwise specified: I
O
= 40 mA, C
I
= 0.33 μF, C
O
= 0.1 μF.
