Special Purpose Regulators Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that the tape and reel packaging matches production line requirements. Ensure compatibility with existing board layouts due to the specific 24-QFN footprint. Check for available lifecycle notices or end-of-life notifications from Renesas Electronics Corporation to mitigate supply chain risks during manufacturing phases.

Special Purpose Regulators Selection Notes

Select this part when designing systems requiring dual high-voltage outputs from a low-voltage input for LCD applications. Consider the thermal performance of the exposed pad in the 4x4mm QFN package. Evaluate the 2.7V to 5.5V input range against the system's primary power source. Verify that the 8V to 20V output range meets the specific biasing needs of the target display panel.
