Electrical Characteristics
C
Note 1 Absolute Maximum Ratings indicate limits beyond which damage to the device may occur Operating Ratings indicate conditions for which the device is
intended to be functional but do not guarantee Specific Performance limits For guaranteed specifications and test conditions see the Electrical Characteristics
Note 2 Refer to Typical Performance Characteristics and Design Considerations for details
Note 3 Regulation is measured at a constant junction temperature by pulse testing with a low duty cycle Changes in output voltage due to heating effects must be
taken into account
