FAN1086M285

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The FAN1086M285 is a low dropout linear regulator manufactured by onsemi, providing a fixed 2.85V output with a maximum current capability of 1.5A. Designed for applications requiring low voltage operation and critical transient response, this device features a TO-263-3 (D2PAK) surface-mount package. It incorporates internal protection mechanisms including trimmed current limiting and on-chip thermal shutdown to safeguard against overload conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Optimized for low voltage environments where minimum input voltage requirements are strict
• Includes on-chip thermal limiting to prevent excessive junction temperatures during overload
• Features trimmed current limit ensuring controlled short-circuit current behavior

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Active Terminators for SCSI bus systems
• Post-regulator stages in power supply chains
• Microprocessor power supply circuits

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

Verify the specific suffix M285 confirms the 2.85V fixed output variant. Confirm the package designation matches the required TO-263-3 footprint. Check manufacturer documentation for RoHS compliance status and any recent product change notifications affecting availability or specifications.

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

Select this component when a precise 2.85V rail is required at up to 1.5A. Ensure the input voltage exceeds the dropout threshold for the expected load current. Consider the thermal performance of the D2PAK package relative to the ambient operating temperature and PCB copper area for heat dissipation.

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

This part belongs to the FAN1086 family of three-terminal adjustable and fixed LDO regulators. The family offers various fixed voltage options alongside an adjustable version, all sharing the same core architecture and protection features while differing in output setpoints and packaging options like SOT-223 and TO-252.

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

Direct substitutes include other FAN1086 variants with different fixed voltages if the voltage level can be adjusted via external resistors, such as the FAN1086M33 or FAN1086M50, provided the pinout and package remain compatible.
