The NSI45030AZ is a Constant Current Regulator & LED Driver 45 V, 30 mA ± 10%, 1.4 W 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. The CCR is based on patent-pending 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 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 AEC-Q101 standard.
