LT1580CQ

Special Purpose Regulators Overview

The LT1580CQ is a high-current, very low dropout positive linear regulator manufactured by Linear Technology. It provides a fixed output voltage of 2.5V with a maximum load current capability of 7A. The device features a dropout voltage as low as 0.8V at full load, ensuring efficient operation even with small input-to-output differentials. It is housed in a 7-pin plastic flat package (PSFM7) designed for surface mount applications.

Special Purpose Regulators Feature Summary

• Very low dropout voltage enables stable regulation with minimal input-output differential
• High current delivery supports demanding power supply requirements
• Fast transient response maintains output stability under dynamic load conditions

Special Purpose Regulators Applications

• Point-of-load regulation for digital signal processors
• Power distribution networks in telecommunications equipment
• Battery-powered systems requiring efficient voltage conversion

Special Purpose Regulators Procurement Notes

Verify the specific suffix and tape-and-reel configuration against the manufacturer's official ordering guide. Confirm that the PSFM7 package dimensions match your PCB footprint requirements. Ensure thermal management solutions are adequate for the expected power dissipation levels during operation.

Special Purpose Regulators Selection Notes

Select this component when a fixed 2.5V output is required with high current capacity. Consider the thermal performance of the PSFM7 package relative to your enclosure constraints. Evaluate the input voltage range to ensure the dropout specification remains within acceptable limits for your application.

Special Purpose Regulators Part Context

This part belongs to the LT1580 family of low dropout regulators, which includes variants offering different output voltages and current ratings.
