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...
