LMS1585A/LMS1587

5A and 3A Low Dropout Fast Response Regulators

General Description

Features

n Fast transient response

The LMS1585A and LMS1587 are low dropout positive regu-

lators with output load current of 5A and 3A respectively.

Their low dropout voltage (1.2V) and fast transient response

make them an excellent solution for low voltage micropro-

cessor applications.

n Available in Adjustable, 1.5V, and 3.3V versions

n Current limiting and thermal protection

n Commercial temp. range

n Industrial temp. range

n Line regulation

0˚C to 125˚C

−40˚C to 125˚C

0.005% (typical)

0.05% (typical)

The LMS1585A/87 are available in adjustable versions,

which can set the output voltage with only two external

resistors. In addition, they are also available in 1.5V and

3.3V fixed voltage versions (Note 9).

n Load regulation

n Direct replacement for LT 1585A/87

™

The LMS1585A/87 circuits include a zener trimmed bandgap

reference, current limiting and thermal shutdown.

Applications

™

n Pentium processor supplies

The LMS1585A/87 series are available in TO-220 and TO-

263 packages.

™

n PowerPC supplies

n Other microprocessor supplies

n Low voltage logic supplies
