LT1307/LT1307B
The
Industrial Grade – 40 C to 85 C. V
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Specifications for commercial (C) grade devices are guaranteed
but not tested at – 20 C. MS8 package devices are designed for and
intended to meet commercial temperature range specifications but are not
tested at – 20 C or 0 C.
Note 3: Bias current flows into FB pin.
