NSI50350AST3G, NSV50350AST3G Constant Current Regulator & LED Driver 50 V, 350 mA 10%, 5.8 W Package www.onsemi.com The linear constant current regulator (CCR) is a simple, economical and robust device designed to provide a costeffective solution for I = 350 mA reg(SS) regulating current in LEDs. The CCR is based on SelfBiased Transistor (SBT) technology and regulates current over a wide voltage Vak = 7.5 V 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. It requires no external components allowing it to be designed as a high or lowside regulator. The high anodecathode voltage rating withstands surges common in Automotive, Industrial SMC 2LEAD and Commercial Signage applications. The CCR comes in thermally CASE 403AC robust packages and is qualified to AEC Q101 standard and UL94V0 Certified. Also available in DPAK: NSI50350ADT4G.
