Note 1: The maximum allowable power dissipation is a function of the maximum junction temperature, T
and the ambient temperature, T
Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown.
Note 2: 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.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5kΩ resistor into each pin.
Note 4: All limits guaranteed at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits are 100%
production tested or guaranteed through statistical analysis. 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 5: Typical numbers are at 25˚C and represent the most likely norm.
Note 6: Duty cycle affects current limit due to ramp generator. See Typical Performance Characteristics for a graph of Power Switch Current Limit vs. V
Switch Current Limit vs. Temp.
Note 7: See Typical Performance Characteristics section for Tri-Temperature data for R
Note 8: Bias current flows into pin.
Note 9: Refer to the graphs titled "Input Offset Voltage vs. Common Mode Voltage".
