ZLDO500 devices, the parts can be damaged
by sustained output shorts or excessive loads
when combined with high input supply
voltages. To ensure reliable operation, keep
loads within the SOA graph boundaries

5). Low Battery Flag
The ZLDO500 provides an output called Low
Battery Flag (LBF). Unlike many regulators

that only signal that they are falling out of
regulation, the LBF output of the ZLDO500
series indicates that the voltage drop across
the regulator has fallen to less than typically
300mV and so supply failure is imminent.
This improved warning gives both more time
for the system supplied to shutdown
gracefully and maintains regulation while
this happens. This could be a vital point if
measurements are under way and must be
