CYT1000A PDF Datasheet – Linear Constant Current IC

A Linear Constant Current IC, also known as a linear current regulator or constant current source IC, is an integrated circuit designed to provide a consistent and precise current output regardless of changes in load resistance or supply voltage. These ICs are commonly used to drive LEDs, lasers, sensors, and other components that require a stable and controlled current.
