The TPS74401 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 will meet the sequencing requirements of FPGAs, DSPs, and other applications with specific start-up requirements.

A precision reference and error amplifier deliver 1% accuracy over load, line, temperature, and process. Each LDO is stable with low-cost ceramic output capacitors and the device is fully specified from –55°C to 125°C.

TIDA-01442 — 适用于 L、S、C 和 X 带的直接射频采样雷达接收器参考设计

此参考设计利用 ADC12DJ3200 评估模块 (EVM) 演示直接射频采样接收器，适用于在 HF、VHF、UHF、L、S、C 和部分 X 带上运行的雷达。模数转换器 (ADC) 的宽模拟输入带宽和高采样率 (6.4GSPS) 可为单通道或双通道 ADC 提供多频带覆盖。该 ADC 具有直接射频采样功能，取消了对多个降压转换级的需求，减少了组件数量，因此降低了系统整体的复杂性。
