ONNSI45015WT1G
Overview
The NSI45015WT1G is a 45V, 15mA constant current regulator designed to provide a simple and cost-effective solution for driving LEDs. Based on Self-Biased Transistor (SBT) technology, this linear regulator maintains a stable current over a wide voltage range and features a negative temperature coefficient to protect LEDs from thermal runaway.
Why Choose This Part
This device eliminates the need for complex external drive circuitry by integrating the current regulation into a compact two-pin SOD-123 package. Its negative temperature coefficient naturally reduces current as temperatures rise, serving as a built-in thermal safeguard for sensitive LEDs.

Key Specifications
Getting Started
When designing with the NSI45015WT1G, ensure the SOD-123 package has adequate copper area on the PCB to manage power dissipation, calculated as the voltage drop across the device multiplied by 15mA. Since it is a two-terminal device, it can be placed in either high-side or low-side configurations without additional biasing components.
