FAN1086M33X

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

The FAN1086M33X is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by onsemi. It provides a stable 3.3 V output with a maximum continuous current of 1.5 A. The device operates within an input voltage range up to 18 V and features a typical dropout voltage of 1.5 V at full load. It includes internal protection mechanisms such as thermal shutdown and current limiting. The regulator is housed in a D2PAK-3 (TO-263-3) surface-mount package, suitable for high-current applications requiring efficient power management.

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific manufacturing lot codes against the latest datasheet revisions. Ensure storage conditions meet semiconductor handling standards to prevent moisture sensitivity issues prior to assembly.

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

Select this component when a fixed 3.3 V rail is required with up to 1.5 A load current. The TO-263-3 package offers superior thermal dissipation compared to smaller SOT packages. Consider input voltage headroom relative to the 1.5 V dropout specification under maximum load conditions to ensure regulation stability.
