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

Verify the manufacturer origin, as Fairchild Semiconductor assets are now managed by onsemi. Confirm the package type matches SOT-223-4 specifications. Ensure the part number suffix indicates the correct fixed 5V output variant. Check for lead-free compliance if required by your assembly process. Validate authenticity through authorized distribution channels to avoid counterfeit components.

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

Select this component when a fixed 5V rail is needed with 1A capacity. Consider the 1.2V dropout requirement relative to your minimum input voltage. Evaluate thermal dissipation needs given the 125°C junction limit. Compare PSRR performance against noise-sensitive application requirements. Verify compatibility with existing PCB footprint constraints for the SOT-223-4 package.

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

This device belongs to the FAN1117A family of three-terminal low dropout regulators. The series includes various fixed output voltages such as 1.8V, 2.5V, 2.85V, 3.3V, and 5V. These regulators share common architectural features including bipolar construction and standard control functions. The family is designed for applications requiring simple, cost-effective voltage regulation solutions.

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

Direct substitutes include other FAN1117AS5X units from different production lots or manufacturers holding the same designation. Cross-reference with onsemi branded equivalents if sourcing from updated inventory. Ensure any replacement maintains identical pinout and electrical characteristics.
