The device regulates to the nominal output voltage under the following conditions:
- The input voltage is greater than the nominal
output voltage plus the dropout voltage (VOUT(nom) +
VDO)
- The headroom across the LDO (VIN - VOUT) is less than
VPHEADROOM for required IOUT, such that power limit is not
engaged
- The output current is less than the current limit
(IOUT < ICL)
- The device junction temperature is greater than
–40°C and less than +150°C
- The device junction temperature is less than the thermal shutdown temperature
(TJ < TSD)
- The enable voltage has previously exceeded the enable rising threshold voltage and has
not yet decreased to less than the enable falling threshold
