Texas Instruments TPS74701 Low-Dropout (LDO) Linear Regulator
Texas Instruments TPS74701 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 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 allows 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 delivers 2% accuracy over load, line, temperature, and process. The device is stable with any capacitor greater than or equal to 2.2µF and is fully specified from -40°C to +125°C. The Texas Instruments TPS74701 is offered in a small 3mm × 3mm VSON-10 package for compatibility with the TPS74801.
