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 — 使用 ADC12DJ3200 的 L、S、C 和 X 帶的直接射頻采樣雷達接收器參考設計

此參考設計利用 ADC12DJ3200 評估模塊 (EVM) 演示直接射頻采樣接收器，適用于在 HF、VHF、UHF、L、S、C 和部分 X 帶上運行的雷達。模數轉換器 (ADC) 的寬模擬輸入帶寬和高采樣率 (6.4GSPS) 可為單通道或雙通道 ADC 提供多頻帶覆蓋。該 ADC 具有直接射頻采樣功能，取消了對多個降壓轉換級的需求，減少了組件數量，因此降低了系統整體的復雜性。
