Status Output (version GS / EJ S only)

The status output ST indicates an overvoltage or undervoltage situation at the regulator’s output Q. Therefore, the

output voltage

V

a low signal at the status output ST. Transients shorter than the status reaction time

t

output.

The status output ST is an open collector output, requiring a pull-up resisitor to a positive voltage rail.
