Product Overview

The LT3070MPUFD#PBF is a low noise low voltage UltraFast™ transient response Linear Regulator with programmable output. The device supplies up to 5A of output current with a typical dropout voltage of 85mV. 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. The 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. The IC incorporates a unique tracking function-to-control a buck regulator powering the LT3070 input. This tracking function drives the buck regulator to maintain the LT3070 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
  • ±1%, ±3% or ±5% Digital output margining
  • ±20% Precision current limit
  • ±1% Accuracy over line, load and temperature
  • 15µF Stable with low ESR ceramic output capacitors
