Diodes AL5809QEV1 Series User Manual

General Description
The AL5809Q is a two terminal constant
current linear LED driver and it provides a
cost-effective solution.
excellent temperature stability 20 ppm/⁰C
and the current accuracy ±5% regulated
over a wide voltage range. The AL5809Q
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 can
swing from 2.5V up to 60V enabling it drive
