The TPS742 series of low-dropout (LDO) linear regulators provide 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 and well suited for powering many different types of processors and ASICs.
The enable input and power-good output allow easy sequencing with external regulators. This
complete flexibility permits the user to configure a solution that meets the sequencing
requirements of FPGAs, DSPs, and other applications with special start-up requirements.
A precision reference and error amplifier deliver 1% accuracy over load, line,
temperature, and process. Each LDO is stable with low-cost ceramic output capacitors, and the
family is fully specified from –40°C to 125°C. The TPS742 devices are offered in a small 5-mm ×
5-mm VQFN (RGW) and a small
3.5-mm × 3.5-mm VQFN (RGR) package, yielding a highly compact total solution size. For
applications that require additional power dissipation, the DDPAK/TO-263 (KTW) package is also
