LT3048IDC-3.3#TRPBF

Overview

The LT3048IDC-3.3#TRPBF is a low noise bias generator with an integrated LDO regulator manufactured by Analog Devices Inc. It utilizes a boost topology to generate a fixed 3.3V output at up to 40mA from an input voltage range of 2.7V to 4.8V. The device operates with a switching frequency of 2.2MHz and features a shutdown pin for power management. It is housed in an 8-lead DFN package and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a low-noise bias generator with an LDO regulator
• Utilizes boost topology for efficient voltage conversion
• Includes a shutdown control feature

Applications

• Bias generation for sensitive analog circuits
• Power supply for low-noise RF components
• Portable electronic devices requiring stable regulation

Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm reel packaging and lead-free status. Confirm availability through authorized distributors as supply may be restricted. Ensure the operating environment remains within the specified temperature limits for reliable performance.

Selection Notes

Select this component when a combined boost converter and LDO solution is required for low-noise applications. The fixed 3.3V output simplifies design compared to adjustable variants. Verify that the input voltage range aligns with the system's power source constraints before integration.

Part Context

This part belongs to the LT3048 series, which combines a step-up switching regulator with a low-dropout linear regulator. The series is designed to provide clean power for noise-sensitive applications. The IDC-3.3 variant specifically provides a fixed 3.3V output, distinguishing it from adjustable or other fixed voltage versions in the family.

Replacement Considerations

LT3048EDC-3.3#TRMPBF offers the same electrical specifications but in a tape-and-reel format instead of cut tape.
