Product Summary

The TPS74401KTWT is a low-dropout (LDO) linear regulator provides an easy-to-use robust power management solution for a wide variety of applications. User-programmable soft-start minimizes stress on the External Bias Supply input power source by reducing capacitive inrush current on start-up. The soft-start is monotonic and well suited for powering many different types of processors and ASICs. The applications of the TPS74401KTWT include FPGA Applications, DSP Core and I/O Voltages, Post-Regulation Applications, Applications with Special Start-Up Time or Sequencing Requirements, Hot-Swap and Inrush Controls.
