Electrical Characteristics (Continued)

Typical values are at T

A = +25˚C. Limits with standard typeface are for TA = +25˚C, and limits in boldface type apply for the

operating temperature range (−40˚C to +85˚C) for LM372_IM5X, and (−40˚C to +125˚C) for LM372_EM5X, unless otherwise

noted. (Note 4)

Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which the device operates

correctly. Operating ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical

Characteristics.

Note 2: The human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin.

Note 3: At elevated temperatures, devices must be derated based on package thermal resistance. The device in the SOT23-5 package must be derated at

4.5mW/˚C at ambient temperatures above 70˚C. The device has internal thermal protection.

Note 4: Production testing done at TA = +25˚C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control

(SQC) methods.

Note 5: RESET Output for LM3722 and LM3724, RESET output for LM3723.

Note 6: Glitches of 100 ns or less typically will not generate a reset pulse.
