6.4.1 Normal Operation

The device regulates to the nominal output voltage under the following conditions:

  • The input voltage is at least as high as VIN(min).
  • The input voltage is greater than the nominal output voltage added to the dropout voltage.
  • The enable voltage is greater than VEN(min).
  • The output current is less than the current limit.
  • The device junction temperature is less than the maximum specified junction temperature.
