Constant Current Regulator  
& LED Driver  
45 V, 20 mA + 15%, 460 mW Package  
The linear 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.

@ Vak = 7.5 V  
The CCR turns on immediately and is at 25% of regulation with  
only 0.5 V Vak. 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. The CCR comes in thermally  
robust packages and is qualified to be UL94−V0 certified.
