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 …
