The CL220 is a temperature compensated, high-voltage constant-current regulator that operates over a wide range of voltages up to 220V. This device operates as a two-terminal constant-current source or sink and is commonly used to drive LEDs with a constant current of 20mA. Multiple CL220s can be used in parallel to increase current capacity. The CL220 comes in a TO-220 package for easy installation and is available in several configurations.
