Procurement Notes

Verify the specific part number suffix against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with your board's thermal design, as the LFCSP package requires adequate copper area for heat dissipation. Confirm that the required output voltage setting aligns with the resistor divider network intended for the SENSE/ADJ pin. Check for any recent product change notices regarding manufacturing location or material composition updates.

Selection Notes

Select this component when a wide input voltage range up to 40 V is necessary alongside a compact footprint. It is suitable for applications demanding low noise and high PSRR in space-constrained designs. Consider the thermal performance of the LFCSP package under maximum load conditions. Verify that the adjustable output capability meets the specific voltage requirements of the target circuit without excessive power dissipation.

Part Context

This component belongs to the ADPL44002 series of low-dropout regulators designed for high-voltage input applications. The series offers a balance of performance and size, utilizing a small LFCSP package. Analog Devices integrates advanced biasing techniques to maintain stability across varying load and line conditions.
