Description for the TPS74401
The TPS74401 low-dropout (LDO) linear regulators provide an easy-to-use robustpower-management solution for a wide variety of applications. The user-programmable soft-startminimizes stress on the input power source by reducing capacitive inrush current on start-up. Thesoft-start is monotonic and well-suited for powering many different types of processors andapplication-specific integrated circuits (ASICs). The enable input and power-good output allow easysequencing with external regulators. This complete flexibility lets the user configure a solutionthat meets the sequencing requirements of field-programmable gate arrays (FPGAs), digital signalprocessors (DSPs), and other applications with specific start-up requirements.
A precision reference and error amplifier deliver 1% accuracy over load, line,temperature, and process. The TPS74401 family of LDOs is stable without an output capacitor or withceramic output capacitors. The device family is fully specified from TJ =–40°C to 125°C. The TPS74401 is offered in two 20-pin smallVQFN packages (a 5-mm × 5-mm RGW and a
3.5-mm × 3.5-mm RGR package), yielding a highly compact total solution size. Forapplications that require additional power dissipation, the DDPAK (KTW) package is alsoavailable.
