LM1084 IC 5A LDO Regulator DIP-3 LM1084

Product Overview

The LM1084 is a high-current, low-dropout (LDO) positive voltage regulator capable of supplying up to 5 A of output current. It is designed to provide a maximum dropout of 1.5 V at full load, ensuring high efficiency. The device is available in fixed output voltage versions (3.3 V and 5.0 V) as well as an adjustable version. It shares the same pinout as the industry-standard LM317, making it a drop-in high-current alternative for many designs.
