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 therma...
