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

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix AD18X matches the required 1.8 V fixed output specification. Check for RoHS compliance status and lead-free soldering requirements relevant to your assembly process. Ensure the TO-252-3 package dimensions align with your PCB footprint design constraints.

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

Select this component when a fixed 1.8 V rail is required with up to 1.5 A load current. Consider the 1.2 V dropout voltage relative to your minimum input supply voltage to ensure proper regulation. Evaluate thermal dissipation capabilities given the 18 W power dissipation rating in the TO-252-3 package. Compare against adjustable LDO options if variable output voltage flexibility is needed instead of a fixed setting.

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

This part belongs to the FAN1086 series of low dropout regulators, which includes variants with different fixed output voltages such as 2.5 V, 2.85 V, 3.3 V, and 5 V. The series is designed for applications requiring high current performance in compact surface-mount packages. It serves as a power management solution within the broader PMIC category offered by Fairchild Semiconductor.

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

Direct substitutes include other FAN1086 variants with identical packaging but different fixed output voltages, such as FAN1086M25X for 2.5 V or FAN1086AS50X for 5 V. Cross-referencing with equivalent 1.5 A LDOs from other manufacturers requires verifying pinout compatibility and thermal performance metrics.
