Descripción de TPS74801
The TPS748 low-dropout (LDO) linear regulator provides 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 designed 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 allows a solution to be configured 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 (new chip) over load, line, temperature, and process. The device is stable with any type of capacitor greater than or equal to 2.2µF, and is fully specified for TJ = –40°C to +125°C. The TPS748 is offered in a small, 3mm × 3mm, VSON-10 package, yielding a highly compact, total solution size. The device is also available in a 5mm × 5mm VQFN-20 package for compatibility with the TPS742.
