TPS74701 单路输出 LDO、500mA、可调节 （0.8 至 3.6V）可编程软启动
TPS74701 描述
The TPS74701 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 well-suited 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 permits the user to configure a solution that meets the sequencing requirements of FPGAs, DSPs, and other applications with special start-up requirements.
A precision reference and error amplifier deliver 2% accuracy over load, line, temperature, and process.
