LMS1585A Datasheet PDF – Linear Voltage Regulator

Part Number: LMS1585A

Function: Low Dropout Fast Response Regulator

Package: TO-220, TO-263 Type

Manufacturer: National (Texas Instruments)


LMS1585A datasheet



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 IC 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 (1).

The device circuits include a zener trimmed bandgap reference, current limiting and thermal shutdown. The device series are available in KTT (TO-263) and NDE (TO-220) packages.


1. Fast Transient Response

2. Available in Adjustable, 1.5V, and 3.3V versions

3. Current Limiting and Thermal Protection
