The Texas Instruments TPS74401KTWR is a 3 A ultra-low-dropout linear regulator in a TO-263 package with an adjustable output from 0.8 V to 3.6 V. Its very low dropout, programmable soft-start and power-good output make it well suited to FPGA core rails and other high-current, low-voltage point-of-load duties.
