TI TPS74801AWDRCR

The TPS748A 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 application-specific integrated circuits (ASICs). The enable input and power-good output allow easy sequencing with external regulators. This complete flexibility enables a solution to be configured that meets the sequencing requirements of field-programmable gate arrays (FPGAs), digital signal processors (DSPs), and other applications with special start-up requirements. A precision reference and error amplifier deliver 0.85% accuracy over load, line, temperature, and process. The device is stable with any type of capacitor greater than or equal to 10 μF, and is fully specified for TJ = -40°C to +125°C. The TPS748A is offered in a small, 3 mm × 3 mm, VSON-10 package, yielding a highly compact, total solution size.
