Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
outside of its stated operating conditions.
Note 2:
All limits are guaranteed at either room temperature (standard type face) or at
temperature extremes (bold typeface)
by production testing or correlation
techniques using standard Statistical Quality Control (SQC) methods.

Note 4:
Load and line regulation are measured at constant junction temperature, using low duty cycle pulse testing (output voltage changes due to heating effects
are covered by the Thermal Regulation specification). For the TO-3 package, load regulation is measured on the output pin,
