  • 2.75V to 5.5V supply voltage
  • 3% output accuracy over temperature/load/line
  • Start-up with pre-biased output
  • Internal digital soft-start - 2ms
  • Soft-stop output discharge during disabled
  • 30µA quiescent supply current in PFM mode
  • Selectable forced PWM mode and PFM mode
  • External synchronization up to 4MHz
  • Typical 6.5µA logic controlled shutdown current
  • 100% maximum duty cycle for lowest dropout
  • Internal current mode compensation
