The TPS743xx low-dropout (LDO) linear regulators provide an easy-to-use robust power management solution for a wide variety of applications. The TRACK pin allows the output to track an external supply. This feature is useful in minimizing the stress on ESD structures that are present between the CORE and I/O power pins of many processors. The enable input and power-good output allow easy sequencing with external regulators. This complete flexibility allows 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 TPS743xx is offered in a small (5mm × 5mm) QFN package, yielding a highly compact total solution size. For applications that require additional power dissipation, the DDPAK (KTW) package is also available.
