Hot-selling and scarce LMS1587IS-ADJ 5A and 3A Low Dropout Fast Response Regulators TO-263-3 spot stock
LMS1587IS-ADJ 5A and 3A Low Dropout Fast Response Regulators TO-263-3 spot stock
Product Descriptions
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 1.5V and 3.3V fixed voltage versions.
The LMS1585A/87 circuits include a zener trimmed bandgap reference, current limiting and thermal shutdown. The LMS1585A/87 series are available in KTT (TO-263) and NDE (TO-220) packages.
