The device regulates to the nominal output voltage
when the following conditions are met:
For the new chip:
- The input voltage is greater than
the nominal output voltage plus the dropout voltage (VOUT(nom) +
VDO)
- The output current is less than
the current limit (IOUT < ICL)
- The device junction temperature
is less than the thermal shutdown temperature (TJ <
TSD)
For the legacy chip:
- The device passes the bias
current to the OUT pin. The load or feedback consumes the minimum load current
captured in the Electrical Characteristics for regulation or the output is potentially too high.
