Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix CF4 corresponds to the X2-WLB0606-4 wafer level chip scale package when sourcing components. Confirm whether the application requires the standard AP7350 variant or the AP7350D version with active output discharge functionality, as these are distinct part numbers despite sharing similar base identifiers. Ensure compatibility with RoHS 3 compliance standards during procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when minimizing board space is critical due to its industry-leading small footprint. Choose this regulator for applications demanding extremely low static power consumption to maximize battery longevity. Verify that the required output voltage matches the fixed 2.5V specification, as adjustable versions are not available in this specific package configuration. Ensure input voltage remains within the specified operational limits.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the AP7350 series of ultra-low quiescent current LDOs from Diodes Incorporated. The series utilizes CMOS process technology to achieve high efficiency and low noise performance. It is specifically engineered for space-constrained environments where traditional SOT packages cannot fit. The family offers various fixed output voltages ranging from 1.2V to 4.5V.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

The AP7350D-25CF4-7 serves as a functional substitute if active output discharge is required upon shutdown. Other AP7350 variants with different output voltages share identical pinouts and packaging but provide different regulated levels. Cross-referencing datasheets is necessary to confirm thermal resistance and electrical characteristics match the original design requirements.
