In summary, onsemi constant current regulators are based on self-biased transistor technology and regulate current over a wide range of voltages. They are designed with a negative temperature coefficient to protect LEDs from thermal runaway at extreme voltages and operating temperatures. They require no external components and their high anode-cathode voltage rating withstands surges in automotive, industrial and commercial applications. CCRs are simple, economical and robust devices designed to provide a cost effective solution for regulating current in LEDs.
