Texas Instruments TPS7A74 Low-Dropout (LDO) Linear Regulator provides an easy-to-use, robust power management solution for various applications. User-programmable soft-start minimizes stress on the input power source by reducing capacitive inrush current on start-up. The soft-start is well-suited and monotonic for powering many types of processors and application-specific integrated circuits (ASICs). The enable input allows for easy sequencing with external regulators. This complete flexibility allows a solution to be configured that meets the sequencing requirements of digital signal processors (DSPs), field-programmable gate arrays (FPGAs), and other applications with special start-up requirements.
A precision reference and error amplifier deliver 1.5% accuracy over load, temperature, line, and process. The device is stable with any type of capacitor greater than or equal to 10µF. It is also fully specified for TJ = –40°C to +125°C. The Texas Instruments TPS7A74 is offered in a small, 3mm × 3mm, WSON-8 package, yielding a highly compact total solution size.
