LMS1585AEP/LMS1587EP
Enhanced Plastic 5A and 3A Low Dropout Fast
Response Regulators
General Description
The LMS1585AEP and LMS1587EP are low dropout posi-
tive regulators with output load current of 5A and 3A respec-
tively. Their low dropout voltage (1.2V) and fast transient
response make them an excellent solution for low voltage
microprocessor applications.
The LMS1585AEP/87EP are available in adjustable ver-
sions, 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 12).
The LMS1585AEP/87EP circuits include a zener trimmed
bandgap reference, current limiting and thermal shutdown.
The LMS1585AEP/87EP series are available in TO-220 and
TO-263 packages.
