The TLF50251EL is an automotive-grade device with a wide input voltage range (4.75 V to 45 V) and operates at 2.2 MHz. It offers efficient power management with features like current limitation, over-temperature shutdown, and adjustable threshold reset output. Its compact design reduces board space while ensuring excellent regulation.

Features

  • 500 mA step down voltage regulator
  • 5 V Output voltage
  • ± 2% output voltage tolerance
  • Low current: < 45μA at nominal voltage
  • Current mode PWM regulation
  • PFM mode for light load current
  • Integrated power transistor
  • 2.2 MHz switching frequency
  • 100% Duty cycle
  • Synchronization input
  • Ultra-low shutdown current: <2μA

Benefits

  • Optimize Vbat systems for consumption.
  • Low drop-out operation due to 100% DC
  • Compensation and soft-start
  • Flexibility in setting reset threshold
  • Versatile family-based design
