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.

Note 3:
Without a heat sink, the thermal resistance of the TO-39 package is about 150C/W, while that of the TO-3 package is approximately 35C/W. With a heat
sink, the effective thermal resistance can only approach the values specified, depending on the efficiency of the sink.
Note 4:
Refer to RETS109H drawing for LM109H or RETS109K drawing for LM109K military specifications.
