Note 4: 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.

temperature, and the regulator will go into thermal shutdown.

Note 6: 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.

Note 7: 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).

Note 8: Typical numbers are at 25˚C and represent the most likely norm.

Note 9: Bias current flows into FB pin.

Note 10: Supply voltage, bias current product will result in aditional device power dissipation. This power may be significant. The thermal dissipation design should

take this into account.
