LT3048EDC-5

Overview

The LT3048EDC-5#TRMPBF is a low noise bias generator with an integrated LDO regulator, manufactured by Analog Devices Inc. It utilizes a boost switching topology to regulate output voltages from a 2.7 V to 4.8 V input range. The device provides a single regulated output of 5 V at up to 40 mA. Operating with a fixed switching frequency of 2.2 MHz, it maintains a typical quiescent current of 475 uA. The component supports a shutdown function and operates within a temperature range of -40°C to +125°C. It is housed in an 8-lead DFN package.

Feature Summary

Integrates a boost converter and LDO regulator for efficient power management
Provides low noise performance suitable for sensitive analog circuits
Supports shutdown functionality for power conservation

Applications

Bias generation for precision analog systems
Power supply stages for low noise sensor interfaces
Embedded systems requiring stable voltage regulation from varying inputs

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when ordering. Confirm the DC-5 variant corresponds to the fixed 5 V output requirement. Ensure compatibility with the 8-DFN footprint during PCB layout. Check manufacturer documentation for latest RoHS compliance status before final procurement approval.

Selection Notes

Select this component when a combined boost and LDO solution is required for low noise applications. The fixed 5 V output eliminates external resistor programming needs. Consider the 2.2 MHz switching frequency for EMI constraints. Verify input voltage stays within the 2.7 V to 4.8 V operational window for proper regulation.

Part Context

This part belongs to the LT3048 series of dual step-up/boost switching and LDO regulators. It shares architectural similarities with other variants like the LT3048EDC-12 but differs in fixed output voltage. The series is designed for applications requiring high efficiency and low noise power delivery in compact packages.
