PRODUCTION DATA.
If the output current at CQ exceeds the internally-set current limit IO(LIM) for a duration longer than tSC, the NFAULT pin is driven logic low to indicate a fault condition. The output is turned off, but the LDO continues to function. The output periodically retries to check if the output is still in the over current condition. In this mode, the output is switched on for tSC in tSCEN intervals. Current fault auto recovery mode can be disabled by setting ILIM_ADJ = OPEN. See Table 5. Toggling EN will clear NFAULT.
