LMS1585
5A and 3A Low Dropout Fast Response Regulators
LMS1585A/LMS1587 and 3A Low Dropout Fast Response Regulators
General DescriptionThe LMS1585Aand LMS1587are low dropout positive regu-
lators with output load currentof 5A and3A respectively.
Their low dropout voltage (1.2V) and fast transient response
make theman excellent solutionfor low voltage micropro-
cessor applications.
The LMS1585A/87 are availablein adjustable versions,
which cansetthe output voltage with only two external resis-
tors.In addition, they are also availableina 3.3V fixed volt-
age version (Note9).
The LMS1585A/87 circuits includea zener trimmed bandgap
reference, current limiting and thermal shutdown.
The LMS1585A/87 series are availablein TO-220 and TO-
263 packages.
Features Fast transient response Availablein Adjustable, 1.5V, and 3.3V versions Current limiting and thermal protection Commercial temp. range 0˚Cto 125˚C Industrial temp. range −40˚Cto 125˚C Line regulation 0.005% (typical) Load regulation 0.05% (typical) Direct replacementfor LT™1585A/87
Applications Pentium™ processor supplies PowerPC™ supplies Other 2.5Vto 3.6V microprocessor supplies Low voltage logic supplies
