CL220
5.0 to 220V operating range (VA-B) 20mA ±10% at 5.0 - 160V 0.01% / °C typical temperature coefficient Available in TO-252 (D-PAK) and TO-220 packages Can be paralleled for higher current
General Description
The Supertex CL220 is a high voltage, temperaturecompensated, 20mA constant current
regulator. The device operates at up to 220V, and is accurate to ±10% over a 5.0 - 160V range. The device can be used as a two terminal constant current source or constant current sink. A typical application for the CL220 is to drive LEDs with a constant current of 20mA. Multiple CL220s can also be used in parallel to provide higher currents such as 40mA, 60mA, 80mA, and so on. The device is available in the TO252 (D-PAK) and TO-220 packages.
