产品说明

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 package, yielding a highly compact total solution size. For applications that require additional power dissipation, the DDPAK/TO-263 (KTW) package is also available.
