  Ultrafast, Low Noise, Low Dropout Linear Regulators
  Running in Parallel Produce Clean, Efficient, High Current
  Point-of-Load Power for FPGA and Server Backplanes
  Kelly Consoer The latest FPGAs and processors have migrated to deep submicron geometries with
  gigahertz+ data rates and integrated telemetry channels that operate from 0.9V to 1.8V
  supply rails. The transient power demand for these processors can reach more than
  10A peak current in nanoseconds. At these processor speeds and high currents even
  the local PCB backplane impedances around the processor can contribute to supply
  droop, where millivolts of supply droop or supply noise can degrade data integrity.
  To manage the system power distribution,
  switching regulators may be used locally
  to downconvert from a higher voltage
  rail. These regulators are traditionally
  bypassed with a large quantity of bulk
  caps to reduce ripple and buffer the load transients. Unfortunately, bulk tantalum
  and electrolytic caps have parasitic ESL and
  ESR that limits their ability to bypass
  fast high current load transients. To a
  lesser extent, even large ceramic caps are
  bandwidth limited by their inherent ESL. The LT3070 and LT3071 family of
  UltraFastв„ў transient response, low noise,
  low dropout linear regulators addresses
  this challenge. The high bandwidths of …
