These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 ensure specific performance limits.
(2) A military RETS specification is available on request. At the time of printing, the LM723 RETS specification complied with the Min and
Max limits in this table. The LM723E, H, and J may also be procured as a Standard Military Drawing.
(3) See derating curves for maximum power rating above 25°C.
