Overview
The CL1N8-G is a linear constant current LED driver IC manufactured by Microchip Technology. It operates within an input voltage range of 5V to 90V DC and provides a fixed output current of 20mA. The device features a single output channel with a constant current accuracy of 5%. It is housed in a TO-243AA (SOT-89) surface-mount package, designed for efficient power management in LED lighting applications requiring stable current regulation.
Feature Summary
- Provides regulated constant current output for LED loads
- Supports wide input voltage range from 5V to 90V
- Utilizes linear topology for simple circuit implementation
Applications
- LED indicator circuits
- Low-power LED lighting modules
- General-purpose LED current regulation
Procurement Notes
Verify the specific suffix G indicates RoHS compliance when sourcing. Confirm the SOT-89 package variant matches your PCB footprint requirements. Ensure the 20mA fixed current rating aligns with your LED specifications. Check datasheet revisions for any updates on thermal performance or electrical limits before finalizing procurement.
Selection Notes
Select this component when a simple, low-cost linear solution is preferred over switching regulators. It is suitable for applications where the voltage drop across the driver does not exceed thermal limits. Consider the 5% current accuracy tolerance for precision requirements. Verify that the 90V maximum input voltage covers your system's operational range.
Part Context
This part belongs to the CL1 series of LED drivers from Microchip Technology. These devices are designed as direct replacements for discrete transistor-based constant current sources. The series offers various current options and packages to suit different LED power levels and form factors.
Replacement Considerations
Direct substitutes may include other 20mA linear LED drivers in SOT-89 packages. Verify pinout compatibility and thermal resistance characteristics. Ensure replacement parts maintain the same 5V-90V input range and 5% accuracy specifications.
