LT3095MPUDD#PBF

Overview

The LT3095MPUDD#PBF is a dual-channel low noise bias generator from Analog Devices Inc. It generates two independent power rails from a common input voltage ranging from 3V to 20V. Each channel integrates a fixed frequency, peak current-mode switching regulator and a low noise, single resistor-programmable linear regulator with a maximum output current of 50mA. The device supports various topologies including SEPIC and boost configurations to accommodate different input-to-output voltage requirements.

Feature Summary

• Dual-channel architecture providing independent low noise bias supplies from a single input source
• Integrated switching regulator combined with a programmable linear regulator for flexible output configuration
• Single resistor programming capability for the linear regulator section

Applications

• Generating low noise bias supplies for analog and mixed-signal circuits
• Powering RF front-ends requiring clean DC sources
• Providing auxiliary power rails in systems with varying input voltages

Procurement Notes

Verify the specific suffix and tape/reel quantity against the official datasheet before ordering. Confirm that the MP grade meets the required temperature and reliability specifications for the target application environment. Ensure compatibility with the intended PCB footprint and thermal management strategy.

Selection Notes

Select this component when dual isolated or related bias rails are needed from a wide input range. Consider the total output current capability and the specific topology (SEPIC vs Boost) required by the input and output voltage differential. Evaluate thermal performance based on the expected load conditions and ambient temperature.

Part Context

This part belongs to the LT3095 family of dual-channel bias generators designed for applications requiring high power supply rejection ratio and low noise. It serves as a solution for powering sensitive components where standard switching regulators may introduce unacceptable ripple or noise into the system.
