LMS1585A 5A/LMS1587 5A and 3A Low Dropout Fast Response Regulators

Check for Samples: LMS1585A , LMS1587

FEATURES

DESCRIPTION

The LMS1585A and LMS1587 are low dropout

234

•

Fast Transient Response

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.

•

Available in Adjustable, 1.5V, and 3.3V

versions

•

Current Limiting and Thermal Protection

Commercial Temp. Tange: 0°C to 125°C

Industrial Temp. Range: −40°C to 125°C

Line Regulation 0.005% (typical)

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⁽¹⁾

Load Regulation 0.05% (typical)

Direct Replacement for LT^®1585A/87

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.
