17) Latch except when Vbb -VOUT < VON(SC) after shutdown. In most cases VOUT = 0 V after shutdown (VOUT ≠

0 V only if forced externally). So the device remains latched unless Vbb < VON(SC) (see page 4). No latch

between turn on and td(SC).

18) With latch function. Reseted by a) Input low, b) Undervoltage, c) Overvoltage

19) Low resistance short Vbb to output may be detected by no-load-detection
