• Internal PWM dimming capability
• Automotive grade qualification

Applications

• General-purpose lighting
• Automotive interior illumination

Procurement Notes

Verify the specific suffix GRLA3 against the official datasheet to confirm package type and tape-and-reel specifications. Confirm AEC-Q100 automotive qualification status if required for your application. Check for any Product Change Notifications (PCN) related to manufacturing site or material changes before finalizing procurement.

Selection Notes

Select this component for single-channel LED driving requirements where linear regulation is acceptable. Ensure the load voltage does not exceed the 42V limit. Consider thermal dissipation capabilities given the linear nature of the driver and the 250mA output current specification.
