LT1580IR-2.5 Description

Short technical summary and product information.

The LT1580IR-2.5 is a high-current, low dropout linear voltage regulator designed for powering modern microprocessors. It can deliver up to 7A of output current with a dropout voltage as low as 540mV at full load.

 

Key features include a fast transient response, which is crucial for stable processor operation, and a remote sense pin. The remote sense functionality virtually eliminates output voltage variations caused by load current changes, ensuring precise voltage delivery at the load.

 

This regulator is suitable for applications requiring stable 2V to 3V supplies, such as powering Pentium or PowerPC processors. It can be used as a post-regulator for switching supplies or as a high-current standalone regulator.

 

The device requires an input voltage that is at least 1V greater than the output voltage for regulation. It is available in adjustable and fixed output versions, with the LT1580IR-2.5 specifically offering a fixed 2.5V output.
