LM1084 5A Low Dropout Positive Regulators

Check for Samples: LM1084

FEATURES

DESCRIPTION

The LM1084 is a series of low dropout voltage

positive regulators with a maximum dropout of 1.5V

at 5A of load current. It has the same pin-out as TI's

industry standard LM317.

•

Available in 3.3V, 5.0V, 12V and Adjustable

Versions

•

Current Limiting and Thermal Protection

Output Current 5A

The LM1084 is available in an adjustable version,

which can set the output voltage with only two

external resistors. It is also available in three fixed

voltages: 3.3V, 5.0V and 12.0V. The fixed versions

intergrate the adjust resistors.

Industrial Temperature Range −40°C to 125°C

Line Regulation 0.015% (typical)

Load Regulation 0.1% (typical)

APPLICATIONS

The LM1084 circuit includes

bandgap reference, current limiting and thermal

shutdown.
