TPS74401RGWR

The TPS74401 low-dropout (LDO) linear regulators
provide an easy-to-use robust power-management
solution for a wide variety of applications. The userprogrammable soft-start minimizes stress on the input
power source by reducing capacitive inrush current
on start-up. The soft-start is monotonic and wellsuited for powering many different types of
processors and application-specific integrated circuits
(ASICs). The enable input and power-good output
allow easy sequencing with external regulators. This
complete flexibility lets the user configure a solution
that meets the sequencing requirements of fieldprogrammable gate arrays (FPGAs), digital signal
processors (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 with ceramic output capacitors.
The device family is fully specified from TJ = –40°C to
125°C. The TPS74401 is offered in two 20-pin small
VQFN packages (a 5-mm × 5-mm RGW and a
3.5-mm × 3.5-mm RGR package), yielding a highly
compact total solution size. For applications that
require additional power dissipation, the DDPAK
(KTW) package is also available.
