DESCRIPTION

· The LMS1585A and LMS1587 are low dropout positive regulators with output load currents of 5A and 3A respectively.

· They feature a low dropout voltage of 1.2V and fast transient response, ideal for low voltage microprocessor applications.

· Available in adjustable versions with output voltage set by two external resistors, and fixed voltage versions of 1.5V and 3.3V.

· Include a zener trimmed bandgap reference, current limiting, and thermal shutdown.

· Offered in KTT (TO-263) and NDE (TO-220) packages.

FEATURES

· Fast transient response for efficient regulation.

· Available in adjustable, 1.5V, and 3.3V versions.

· Current limiting and thermal protection for enhanced safety.

· Operates in commercial temperature range of 0°C to 125°C and industrial range of -40°C to 125°C.

· Excellent line regulation of 0.005% and load regulation of 0.05% typical.

· Direct replacement for LT®1585A/87 series.

APPLICATIONS

· Supplies for Pentium® processors.

· PowerPC® processor supplies.

· Other microprocessor supplies.

· Low voltage logic supplies.
