NSI45015W: LED Driver, Constant Current Regulator, 15 mA, 45 V

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 regulate 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 35% 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 AEC-Q101 standard, and UL94-V0 certified.
