... INTERNAL LOGIC THRESHOLD THERMAL CONSIDERATIONS SY ~ 1.4V The LT1795 contains a thermal shutdown feature that protects against excessive internal (junction) temperature. 1795 F07 If the junction temperature of the device exceeds the protection threshold, the device will begin cycling between normal operation and an off state. The cycling is not harmful to the part ...
