Product Summary
The TPS74901RGWR 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 input power source by reducing capacitive inrush current on start-up. The soft-start is monotonic andfor Other Supplies well-suited for powering many different types of processors and ASICs. The applications of the TPS74901RGWR 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.
