TPS74901DRCR

具有电源正常指示和使能功能的 3A、低输入电压 0.8V、可调节超低压降稳压器 10-VSON -40 to 125

The TPS74901 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 during 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. The device is stable with any type of capacitor ≥ 2.2 µF, and the device is fully specified from –40°C to 125°C. The TPS74901 is offered in a small 3 mm × 3 mm VSON package and a small 5-mm × 5-mm VQFN package, yielding a highly compact total solution size. The device is also available in a DDPAK-7 package.
