SK40279001 Datasheet Another possible stability problem that can occurin mono- lithic IC regulators is current limit oscillations. These can occur because in current limit the safe area protection exhibits a negative impedance. The safe area protection decreases the current limit as the input-to-output voltage increases.That is the equivalent of having a negitive resis- tance since increasing voltage causes currentto decrease. Negitive resistance during currentlimit is not unique to the LT1083 series and has been present on all power IC regulators. The value of negative resistance is a function of how fast the current limit is folded back as input-to- SK40279001 Price| | | | | | | | | | | | | | | | | | | | | | 1 | | | | | | | | | | | | | | I | | | | | | | | | | | | 1 | | | | | | | | | | | | | | | | | | | | | | | | | I | | | | | | | | | | | | | 1 | | | | | | | | | TA | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ij | I | | | 40 0 40 80 120 0C 2( _T | | | | | | | | | | | | |
