LTM8080EY#PBF

LTM8080EY#PBF is a dual 500mA or single 1A ultralow noise, ultrahigh PSRR µModule® regulator. It has a cascaded architecture that contains a 40VIN step-down silent switcher regulator with an integrated EMI noise shield followed by dual high-performance low-dropout linear regulators. The dual LDOs feature ADI’s ultralow noise and ultrahigh PSRR architecture for powering noise-sensitive applications. This is an integrated solution comprised of a switcher and LDOs, it offers both advantages while maintaining a small size and significantly reduced PCB layout sensitivity. Application includes RF power supplies is PLLs, VCOs, Mixers, LNAs, very low noise instrumentation, high speed/high precision data converters, medical applications like imaging, diagnostics.
