LT3048EDC-5#TRPBF

Overview

The LT3048EDC-5#TRPBF is a low noise bias generator with an integrated LDO regulator, manufactured by Analog Devices Inc. It utilizes a boost topology to step up the input voltage range of 2.7 V to 4.8 V for stable operation. The device provides a fixed output voltage of 5 V with a maximum output current capability of 40 mA. Operating at a switching frequency of 2.2 MHz, it maintains a typical quiescent current of 475 uA. The component is housed in an 8-pin DFN package and supports a wide operating temperature range from -40 C to +125 C.

Feature Summary

• Integrates a boost converter with a linear regulator to provide low noise power supply generation.
• Supports input voltages below the regulated output level through internal boosting circuitry.
• Features a compact surface-mount package suitable for space-constrained designs.

Applications

• Biasing sensitive analog circuits requiring low noise power supplies
• Powering precision reference sources in measurement equipment
• Providing clean power rails for microcontroller peripherals

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and tape specifications. Ensure the ordering part number matches the required reel configuration. Confirm RoHS compliance status and material declarations prior to procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and availability status.

Selection Notes

Select this component when input voltage may drop below the required output level during operation. Consider the 40 mA output limit for load requirements. Evaluate thermal performance within the specified temperature range. Verify compatibility with the 2.2 MHz switching frequency regarding EMI constraints in the target application environment.
