onsemi Integrated Circuits (ICs) - Power Management (PMIC) - Current Regulation/Management NSV45035JZT1G

The 1320296-NSV45035JZT1G is an adjustable constant current regulator designed for LED driving applications. It operates within a wide voltage range of up to 45 V and can regulate output currents between 35 mA and 70 mA with an accuracy of ±15%. The device utilizes Self-Biased Transistor (SBT) technology, which allows for immediate turn-on at low voltage levels (0.5 V Vak) and features a negative temperature coefficient to prevent thermal runaway in LEDs. This regulator is suitable for various applications, including automotive lighting, display signage, and decorative lighting. It is packaged in a thermally robust SOT-223 package and is compliant with AEC-Q101 standards, making it suitable for automotive environments. The device is also RoHS compliant and uses halogen-free materials. The Radj pin allows for current adjustment by connecting an external resistor, although it can be left unconnected if no adjustment is needed. Overall, this product offers a reliable solution for current regulation in LED applications.
