FAN1086M33

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

The FAN1086M33 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 features a typical dropout voltage of 1.5 V at full load and operates within an input voltage range supporting this regulation. It includes internal protection mechanisms such as thermal shutdown and current limiting to ensure reliability under fault conditions. The component is housed in a D2PAK-3 (TO-263-3) surface-mount package, suitable for applications requiring efficient power management in compact designs.

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

Verify the specific suffix M33 confirms the 3.3 V fixed output variant. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the TO-263-3 package footprint matches PCB design constraints. Check for any recent product change notifications regarding manufacturing sites or materials. Validate operating temperature ranges against application environmental requirements.

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

Select this component when a stable 3.3 V rail is required from higher input voltages. Consider the 1.5 A current limit for load demands. Evaluate thermal performance based on ambient temperature and PCB copper area for heat dissipation. Compare dropout voltage specifications against minimum input voltage availability. Verify package compatibility with automated assembly processes.

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