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. The device is is stable with any type of capacitor greater than or equal to 2.2µF (new chip), and is fully specified from –40°C to 125°C.
