Texas Instruments TPS74801DRCR

TPS74801DRCR Description
The TPS74801DRCR low-dropout (LDO) linear regulator is an easy-to-use, reliable power management solution that may be used in a wide range of applications. By decreasing capacitive inrush current on startup, user-programmable soft-start reduces stress on the input power supply. The soft-start is consistent, making it ideal for powering a wide range of processors and ASICs. The enabled input and power-good output make external regulator sequencing simple. The customer can create a solution that fulfills the sequencing needs of FPGAs, DSPs, and other applications with particular start-up requirements thanks to this total freedom.
