The SM2082G is a SOT-89-3, RoHS-compliant LED driver manufactured by Sunmoon. It is a three-terminal, non-isolated integrated circuit designed for driving strings of LEDs up to 150 mA with constant current. Its 1.6V to 5.5V input voltage range make it suitable for a wide range of applications. The SM2082G has an adjustable LED current output of 20mA up to 150mA. It also features low ripple current, low output voltage, high efficiency, and low-temperature shutdown. The SM2082G also offers current limiting protection to ensure safety and reliability in application. It is also designed for a low electromagnetic interference level and noise immunity.
