LMS1585 - 5A and 3A Low Dropout Fast Response Regulators

Datasheet Summary

Description

The LMS1585A and LMS1587 are low dropout positive regulators 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 microprocessor applications.

LMS1585A/LMS1587 5A Low Dropout Fast Response Regulators April 2000 LMS1585A/LMS1587 5A and 3A Low Dropout Fast Response Regulators General Description The LMS1585A and LMS1587 are low dropout positive regulators 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 microprocessor 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 a 3.3V fixed voltage version (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 TO263 packages.
