Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the

device is intended to be functional, but device parameter specifications may not be guaranteed. For guaranteed specifications and test

conditions, see the Electrical Characteristics.

the regulator will go into thermal shutdown.

(5)

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

Ω resistor into each pin. The machine model is a 200pF

capacitor discharged directly into each pin.

Operating Conditions

−40°C to +125°C

All limits guaranteed at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits

are 100% production tested. All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control

(SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
