This article introduces a new type of linear regulator that uses parallel operation to provide clean, efficient, high-current point-of-load power for FPGA and server backplanes. This regulator has a fast transient response, low output voltage noise, and low output voltage drop.
The article introduces the LT3070 and LT3071 family of UltraFast transient response, low noise, low dropout linear regulators designed to address power supply challenges in high-speed FPGAs and processors. These devices operate from 0.9V to 1.8V supply rails and can deliver up to 5A of output current with a typical dropout voltage of 85mV.
The linear regulator supplies up to 5A of output current.
The LT3070 has a typical dropout voltage of 80mV.
Eight LT3070s have successfully been paralleled to share a common load.
