Description

The AL5809Q is a constant current linear LED driver and provides a cost-effective two pin solution. It offers an excellent temperature stability 20 ppm/°C and the current accuracy ±3% regulated over a wide voltage range. The AL5809 simplifies the design for linear LED drivers allowing it to be designed as a high or low-side constant current regulator without any external components.

The AL5809Q turns on immediately and its 60V Voltage rating between Input and Output pins swing enables it drive long LED chains.
