LM1085ISX-3.3 3.3V 3A LDO Voltage Regulator with 1.5V Dropout ±2% Accuracy Current/ Thermal Limit TO-263 Package -40°C to +125°C for Industrial & Commutator Apps


Features

• Available in 3.3-V, 5.0-V, 12-V and Adjustable 1 Versions

• Current Limiting and Thermal Protection

• Output Current 3 A

• Line Regulation 0.015% (typical)

• Load Regulation 0.1% (typical)


Applications

• High Efficiency Linear Regulators

• Battery Charger

• Post Regulation for Switching Supplies

• Constant Current Regulator

• Microprocessor Supply


Description

The LM1085 is a regulator with a maximum dropout of 1.5 V at 3 A of load current. It has the same pin out as TI's industry standard LM317.

Two resistors are required to set the output voltage of the adjustable output voltage version of the LM1085. Fixed output voltage versions integrate the adjust resistors.

The LM1085 circuit includes a zener trimmed bandgap reference, current limiting and thermal shutdown.

Refer to the LM1084 for the 5A version, and the LM1086 for the 1.5A version.
