NSI45030AT1G Description

Short technical summary and product information.

The NSI45030AT1G is a constant current regulator designed to supply a steady 30 mA current to LED strings or other loads. It operates with an anode-cathode voltage up to 45 V and maintains regulation with ±10% accuracy. This device is housed in a surface-mount SOD123 package, suitable for automated assembly.

 

Typical applications include LED lighting, battery charging, and current limiting in automotive and industrial circuits. The regulator provides a simple two-terminal solution for constant current sourcing, requiring no external components. Its negative temperature coefficient helps protect LEDs from thermal runaway.
