TPS74801-Q1中文资料具有电源正常指示功能的汽车类 1.5A、低输入电压 (0.8V)、可调节超低压降稳压器数据手册TI规格书

描述 Description

The TPS74801-Q1 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. The device is stable with any type of capacitor greater than or equal to 2.2 µF, and is fully specified from –40°C to 105°C for the DRC package, and from –40°C to 125°C for the RGW package. The TPS74801-Q1 is offered in a small 3-mm × 3-mm SON-10 package, yielding a highly compact, total solution size. It is also available in a 5 × 5 QFN-20 for compatibility with the TPS74401.
