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.

= 20W.
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.
