LTM8080 Series

The LTM8080 is a 40VIN, dual 500mA or single 1A ultralow noise, ultrahigh PSRR μModule®regulator. LTM8080 has cascaded architecture which contains a 40VINstep-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. The LTM8080 is an integrated solution comprised of a switcher and LDOs, which offers both advantages while maintaining a small size and significantly reduced PCB layout sensitivity.The package includes the controllers, power switches, inductors, and support components. In addition, the LTM8080 has a built-in voltage tracking function that automatically sets VBUSto either 2.5V nominal or 1V higher than VOUT1, whichever is greater, to achieve superior noise performance and minimize power dissipation.The LTM8080 is packaged in a thermally enhanced, compact (9mm × 6.25mm × 3.32mm) over-molded Ball Grid Array (BGA) package suitable for automated assembly by standard surface mount equipment and is RoHS compliant.APPLICATIONSRF Power Supplies: PLLs, VCOs, Mixers, LNAsVery Low Noise InstrumentationHigh Speed/High Precision Data ConvertersMedical Applications: Imaging, DiagnosticsProtected by U.S. patents, including 11258356B2.
