The status output ST indicates an overvoltage or undervoltage situation at the regulator’s output Q. Therefore, the
output voltage
a low signal at the status output ST. Transients shorter than the status reaction time
output.
The status output ST is an open collector output, requiring a pull-up resisitor to a positive voltage rail.
