The TPS74701-Q1 low-dropout (LDO) linear regulator provides an easy-to-use, robust power management solution for a wide variety of applications. The user-programmable soft-start minimizes stress on the input power source by reducing capacitive inrush current and the monotonic start-up is designed for powering many different types of processors and ASICs. The enable input and power-good output allow easy sequencing with external regulators, allowing a solution to be configured that meets the sequencing requirements for a wide range of applications with special start-up requirements.

A precision reference and error amplifier deliver 0.95% accuracy over load, line, temperature, and process. The device is stable with any type of capacitor greater than or equal to 2.2 µF, and is fully specified per AEC-Q100.
