LT1580CR-2.5#PBF

Special Purpose Regulators Overview

The LT1580CR-2.5#PBF is a low dropout positive linear regulator manufactured by Analog Devices Inc., designed for applications requiring high current output with minimal voltage drop. This specific variant provides a fixed 2.5V output and supports up to 7A of load current. It operates within an input voltage range of 3V to 25V, ensuring stable regulation under varying supply conditions. The device features internal thermal overload protection and current limiting to safeguard against fault conditions. Packaged in a 16-Lead SOIC (N) surface-mount format, it is suitable for space-constrained designs. The component is rated for operation over an industrial temperature range of -40°C to +125°C, providing reliability in demanding environments.

Special Purpose Regulators Procurement Notes

Verify the exact suffix 'CR' corresponds to the specified temperature grade and package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Special Purpose Regulators Selection Notes

Select this part when a fixed 2.5V rail is required at currents up to 7A. Ensure the input voltage remains within the 3V to 25V operational window. Consider the thermal performance of the SOIC-16 package and implement adequate PCB copper area for heat dissipation to maintain safe junction temperatures under full load.

Special Purpose Regulators Part Context
