... The SA305 has an internal FAULT latch mechanism by which the device stays disabled (in case a fault occurs) un- less the user resets it. If the SA305 goes into FAULT condition because of short-circuit, over current or high temperature, the DISABLE pin needs to be pulled HIGH (briefly) to reset the SA305 and resume normal operation ...
