LMS1585A/LMS1587
5A and 3A Low Dropout Fast Response Regulators
General Description
The LMS1585Aand 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.
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).
The LMS1585A/87 circuits include a zener trimmed bandgap
reference, current limiting and thermal shutdown.
The LMS1585A/87 series are available in TO-220 and TO-
263 packages.
