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

Verify the manufacturer origin as Fairchild Semiconductor or its successor entities due to corporate acquisitions. Confirm RoHS compliance status for specific production lots, as older batches may differ. Ensure the TO-220 package variant matches design requirements. Check for obsolescence notices from onsemi, which acquired Fairchild's semiconductor business.

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

Select this component when a fixed 1.5V rail is required with high current capability. Compare dropout characteristics against system input voltage ranges to ensure regulation stability. Consider thermal dissipation requirements given the 3A output capacity in a TO-220 package. Verify pinout compatibility if replacing existing designs.

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

This part belongs to the FAN1585 series of LDO regulators, which includes adjustable and other fixed voltage variants. The series is designed for applications requiring low noise and high ripple rejection. The 'AT' suffix typically denotes the TO-220 package type, while '15' indicates the 1.5V fixed output voltage.

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

Direct substitutes include other 3A 1.5V LDOs in TO-220 packages. Verify electrical parameters such as dropout voltage and load regulation match original specifications. Cross-reference with onsemi documentation for equivalent parts within the same product family.
