  • Power-good (PG) output with 1ms delay
  • 2.8V to 5.5V supply voltage
  • 3% output accuracy over temperature/load/line
  • Start-up with pre-biased output
  • 40µA quiescent supply current in PFM mode
  • Selectable forced PWM mode and PFM mode
  • External synchronization up to 8MHz
  • Typical 6.5µA logic controlled shutdown current
  • 100% maximum duty cycle for lowest dropout
  • Internal current mode compensation
