AL5819 36V LOW DROPOUT LINEAR LED DRIVER Description The DIODES™ AL5819 is 36V Low Dropout Linear LED driver offering excellent temperature stability and adjustable output current handling capability. The AL5819 simplifies the design of linear and isolated or non-isolated LED drivers by setting the LED current with standard value resistors. It is a simple and elegant solution to deliver constant current for a single LED string. Pin Assignments SOT26 (Type SM) NC 1 6 LED The AL5819 has an open drain output that can swing up to 36V enabling it drive long LED chains. Its RSET pin is outside of the LED current path and regulated accuracy while minimizing the required overheads to regulate the LED current. This reduces its power dissipation when compared to traditional linear LED drivers.
