LTM8080: 40VIN, Dual 500mA or Single 1A Ultralow Noise, Ultrahigh PSRR μModule® Regulator

The LTM8080 is a 40VIN, dual 500mA or single 1A ultralow noise, ultrahigh PSRR μModule regulator. LTM8080 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 LTM8080’s dual LDO regulators feature ADI’s ultralow noise and ultrahigh PSRR architecture for powering noise-sensitive applications. It is an integrated solution comprised of a switch regulator and LDO regulators, which offers both advantages while maintaining a small size and significantly reduced PCB layout sensitivity.

Key Features and Benefits

• Ultrahigh PSRR of 80 dB at 100 kHz for noise supply rejection and reduction of output ripple
• Ultralow spot noise and output voltage noise of 2 nV/√Hz at 10 kHz to generate a clean supply
• Silent Switcher architecture with an integrated EMI noise shield

Applications

• General Purpose: Low noise power supply for RF devices, transceivers, mixers, modulators, and sensors
• Instrumentation and Measurement
• Communications
• Healthcare

Evaluation Board

The LTM8080 can be evaluated with the DC3071A.
