Product Overview

The LT3071EUFD#PBF is a low voltage low noise UltraFast™ transient response Linear Regulator with analog margining and programmable output. A 0.01µF reference bypass capacitor decreases output voltage noise to 25µVRMS. Its high bandwidth permits the use of low ESR ceramic capacitors, saving bulk capacitance. It features make it ideal for high performance FPGAs, microprocessors or sensitive communication supply applications. Output voltage is digitally selectable in 50mV increments over a 0.8 to 1.8V range. An analog margining function allows the user to adjust system output voltage over a continuous ±10% range. The IC incorporates a unique tracking function to control a buck regulator powering the input. This tracking function drives the buck regulator to maintain the LT3071 input voltage to VOUT + 300mV, minimizing power dissipation. Internal protection includes UVLO, reverse-current protection, precision current limiting with power fold-back and thermal shutdown.
  • Enable function turns output ON/OFF
  • VIOC pin controls buck converter to maintain low power dissipation and optimize efficiency
  • PWRGD/UVLO/Thermal shutdown flag
  • ±20% Precision current limit
  • IMON = IOUT/2500 Output current monitor
  • ±1% Accuracy over line, load and temperature
  • 15µF Stable with low ESR ceramic output capacitors
