Adjustable Constant Current  
Regulator & LED Driver  
45 V, 20 − 40 mA + 15%, 1.5 W Package  
The adjustable constant current regulator (CCR) is a simple,  
economical and robust device designed to provide a cost effective  
solution for regulating current in LEDs (similar to Constant Current  
Diode, CCD). The CCR is based on Self-Biased Transistor (SBT)  
technology and regulates current over a wide voltage range. It is  
designed with a negative temperature coefficient to protect LEDs from  
thermal runaway at extreme voltages and currents.

The CCR turns on immediately and is at 20% of regulation with  
only 0.5 V Vak. The R pin allows I

(Pin 4). The R pin can also be left open (No Connect) if no

adjustment is required. It requires no external components allowing it  
to be designed as a high or low−side regulator. The high anode-  
cathode voltage rating withstands surges common in Automotive,  
Industrial and Commercial Signage applications. This device is  
available in a thermally robust package and is qualified to stringent  
AEC−Q101 standard, which is lead-free RoHS compliant and uses  
halogen-free molding compound, and UL94−V0 certified.
