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 2: Unless otherwise specified, these specifications apply −55˚C

≤ Tj ≤ +150˚C for the LM109 and 0˚C ≤ Tj ≤ +125˚C for the LM309; VIN = 10V; and IOUT = 0.1A

for the TO-39 package or IOUT = 0.5A for the TO-3 package. For the TO-39 package, IMAX = 0.2A and PMAX = 2.0W. For the TO-3 package, IMAX = 1.0A and PMAX

= 20W.

Note 3: Without a heat sink, the thermal resistance of the TO-39 package is about 150˚C/W, while that of the TO-3 package is approximately 35˚C/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.
