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 — Receptor de radar de muestreo directo de RF para diseño de referencia en bandas L, S, C y X

This reference design uses the ADC12DJ3200 evaluation module (EVM) to demonstrate a direct RF-sampling receiver for a radar operating in HF, VHF, UHF, L-, S-, C- and part of X-band. The wide analog-input bandwidth and high-sampling rate (6.4 GSPS) of the analog-to-digital converter (ADC) provides (...)
