7.4.1 Normal Operation

The device regulates to the nominal output voltage when the following conditions are met:

  • 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(shutdown))
  • The voltage on the EN_UV pin has previously exceeded the VIH(EN_UV) threshold voltage and has not yet decreased to less than the VIL(EN_UV) falling threshold
