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.

레퍼런스 디자인

TIDA-01442 — ADC12DJ3200을 사용하는 L, S, C 및 X 대역을 위한 직접 RF 샘플링 레이더 수신기 레퍼런스 디자인

이 레퍼런스 디자인은 ADC12DJ3200 평가 모듈(EVM)을 사용하여 HF, VHF, UHF, L-, S- 및 C- 및 X-밴드의 일부에서 레이더 작동에 사용되는 직접 RF 샘플링 리시버를 시연합니다. 아날로그-디지털 컨버터(ADC)의 넓은 아날로그 입력 대역폭 및 높은 샘플링 속도(6.4GSPS)는 단일 또는 듀얼 ADC로 다중 대역 범위를 제공합니다. ADC의 직접 RF 샘플링 기능은 여러 다운 변환 단계를 제거하여 구성 요소 수를 줄이고 전반적인 시스템 복잡성을 줄입니다.
