FAN1086S5X

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

The FAN1086S5X is a low dropout linear regulator manufactured by Fairchild Semiconductor, part of the FAN1086 series. It provides a fixed 5V output with a maximum load current capability of 1.5A. The device utilizes a SOT-223 surface-mount package (TO-263 variant). Key electrical characteristics include a typical load regulation of 0.05% and integrated thermal limiting protection to prevent excessive junction temperatures under overload conditions.

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

Verify component authenticity through authorized distribution channels due to potential obsolescence status. Confirm package marking codes match official datasheet specifications. Check for RoHS compliance variations across manufacturing lots. Validate supplier documentation against original Fairchild Semiconductor data sheets before integration into production designs.

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

Select this component when a fixed 5V rail is required with 1.5A capacity in a compact SMD form factor. Ensure input voltage exceeds the minimum dropout requirement for the expected load current. Consider thermal management solutions given the TO-263 package constraints under high power dissipation scenarios compared to lower current alternatives.
