(1) Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.
(2) TPS20x1B and TPS20x2B devices in the D, DGN, and DBV packages do not have overcurrent trip thresholds. Current is limited to IOS under different test condition. Check Section 8.3.7 for more details.
(3) The thermal shutdown only reacts under overcurrent conditions.
