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: These specifications apply for 55C
≤ TA ≤ +125C for the LM129 and 0C ≤ TA ≤ +70C for the LM329 unless otherwise specified. The maximum junction
temperature for an LM129 is 150C and LM329 is 100C. For operating at elevated temperature, devices in TO-46 package must be derated based on a thermal re-
sistance of 440C/W junction to ambient or 80C/W junction to case. For the TO-92 package, the derating is based on 180C/W junction to ambient with 0.4" leads
from a PC board and 160C/W junction to ambient with 0.125" lead length to a PC board.
Note 3: Refer to RETS129H for LM129 family military specifications.
Note 4: These changes are tested on a pulsed basis with a low duty-cycle. For changes versus temperature, compute in terms of tempco.
