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
The electrical characteristics data represent pulse test conditions with junction temperatures as shown at the initiation of tests
Note 3
The temperature coefficient of VOUT is typically within 001% VO C
