CL2  
Simple 90V, 20mA, Temperature Compensated  
Constant Current LED Driver IC  
Features  
General Description  
TheSupertexCL2isahighvoltage,temperaturecompensated,  
constant current source. The device is trimmed to provide  
a constant current of 20mA±10% at an input voltage of 5.0  
- 90V. The device can be used as a two terminal constant  
current source or constant current sink.  
► 5.0 to 90V operating range (VA-B)  
► 20mA ±10% at 5.0 - 90V  
► 0.01%/°C typical temperature coefficient  
► Available in TO-243AA (SOT-89), TO-252 (D-PAK),  
& TO-92 packages  
► Can be paralleled for higher current  
Atypical application for the CL2 is to drive LEDs with a constant  
current of 20mA. Multiple CL2s can also be used in parallel to  
provide higher currents such as 40mA, 60mA or 80mA. The  
device is available in TO-243AA (SOT-89), TO-252 (D-PAK),  
and TO-92 packages.  
Applications  
► LED driver  
► Industrial lamp indicators  
► Signage  
► Accent lighting  
► Automotive  
► Constant current source  
► Constant current sink
