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

Verify the exact suffix designation against the manufacturer's official documentation to confirm package type and electrical tolerances. Ensure that the procurement source provides valid traceability data. Confirm RoHS compliance status as per the latest product change notification. Cross-reference the part number with the distributor's inventory system to avoid obsolete stock issues.

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

Select this component when a precise 2.85V rail is required for legacy interface compatibility or specific memory termination. Evaluate the thermal performance within the target enclosure to ensure junction temperatures remain within safe operating limits. Consider the 7.5V maximum input rating to guarantee adequate headroom without exceeding absolute maximum ratings during transient events.

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

This part belongs to the FAN1086 family of three-terminal adjustable and fixed low dropout regulators. The series is characterized by its ability to handle high currents while maintaining stability in low voltage environments. The S285 variant specifically targets the 2.85V output requirement, distinguishing it from other fixed voltage options like 2.5V, 3.3V, or 5.0V within the same product line.

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

Compatible substitutes include the LM1086CSX-3.3-NOPB for similar current capabilities with different voltage output, or the FAN1086M25X for alternative fixed voltage options within the same package family. Verify pinout compatibility and thermal resistance values before implementing any cross-brand replacement.
