Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.

= 0.5A for the TO-3 and TO-220 packages. Although power dissipation is internally limited, these specifications are
applicable for power dissipations of 2W for the TO-39 and 20W for the TO-3 and TO-220. I
MAX
is 1.5A for the TO-3 and TO-220 and 0.5A for the TO-39 package.
Note 3:
Regulation is measured at constant junction temperature. Changes in output voltage due to heating effects must be taken into account separately. Pulse test-
ing with low duty cycle is used.
Note 4:
Refer to RETS117HVH for LM117HVH or RETS117HVK for LM117HVK military specificatioins.
Note 5:
