The LT1580IQ#PBF from Analog Devices is a high-current, low-dropout voltage regulator capable of delivering up to 7A. Designed to power modern microprocessors, it features a low dropout voltage of just 540mV at its maximum output current.
This regulator boasts fast transient response and includes a remote sense pin, which helps to virtually eliminate output voltage variations caused by load changes. The typical load regulation is less than 1mV for a load current step from 100mA to 7A. The device supports adjustable output voltages ranging from 1.25V to 4.65V.
Packaged in a 5-DDPAK (TO-263-6, D²Pak) surface-mount package, the LT1580IQ#PBF operates within a junction temperature range of -40°C to 125°C (control section) and -40°C to 150°C (power transistor). Its applications include microprocessor supplies, post regulators for switching supplies, and high-current regulation.
Key electrical characteristics include a maximum VCONTROL input voltage of 13V and a maximum VPOWER input voltage of 6V. The fixed 2.5V output version is also available, making it suitable for various processor supply requirements.
