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 noted, specifications apply for −55˚C

LM323. Although power dissipation is internally limited, specifications apply only for P

≤ 30W.

Note 3: Without a heat sink, the thermal resistance of the TO-3 package is about 35˚C/W. With a heat sink, the effective thermal resistance can only approach the

specified values of 2˚C/W, depending on the efficiency of the heat sink.

Note 4: Load and line regulation are specified at constant junction temperature. Pulse testing is required with a pulse width

≤ 1 ms and a duty cycle ≤ 5%.

Note 5: Refer to RETS123K drawing for LM123K military specifications.

Note 6: Human body model, 1.5 k

Ω in series with 100 pF.
