LT1580IR-2.5 Description

Short technical summary and product information.

The LT1580IR-2.5 is a 7A low dropout linear voltage regulator designed for powering modern microprocessors. It features a low dropout voltage, reaching only 540mV at its maximum output current of 7A. This device also boasts fast transient response and excellent load regulation, with variations of less than 1mV for a load current step from 100mA to 7A.

 

With a fixed 2.5V output, the LT1580IR-2.5 is suitable for applications requiring stable voltage rails, such as microprocessor supplies on motherboards. It operates with an input voltage up to 6V and a control input voltage up to 13V. The regulator is designed to prevent supply sequencing problems in dual supply modes.

 

Key electrical characteristics include a typical output voltage of 2.5V, a maximum output current of 7A, and a maximum input voltage of 6V. The operating junction temperature range for the control section is 0°C to 125°C, and for the power transistor, it is 0°C to 150°C.

 

This regulator is ideal for post-regulation of switching supplies and high-current regulation needs. Its design facilitates generating processor supplies of 2V to 3V on motherboards where 5V and 3.3V supplies are available, and it is also suitable for 3.3V to 2.9V conversions for portable processors.
