DIOAL5809-15S1-7
Overview
The AL5809-15S1-7 is a constant-current LED driver designed for simplicity and stability in a compact SOD-123 package. It provides a fixed 15mA output from a wide supply voltage range of 2.5V to 60V, acting as a robust alternative to discrete resistor-based solutions. This linear driver offers high power supply rejection and low temperature drift to maintain consistent LED brightness across varying operating conditions.
Why Choose This Part
This device eliminates the need for external current-setting resistors, reducing both PCB real estate and BOM complexity. Its high 60V rating allows for long LED series strings, while the SOD-123 package provides a tiny 2.65mm by 1.55mm footprint for high-density designs.
Applications
Key Specifications
Getting Started
To implement the AL5809-15S1-7, connect the input pin to the DC supply and the output pin to the anode of the LED string. Ensure the total voltage drop across the LED string plus the minimum 2.5V overhead is within the supply voltage limits. Use adequate PCB copper pours around the SOD-123 package to manage thermal dissipation during high-voltage-drop operation.
