FAN2559S10X

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

The FAN2559S10X is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Fairchild Semiconductor, now part of onsemi. It provides a fixed 1V output with a maximum load current of 180mA. The device operates within an input voltage range of 2.7V to 5.5V and features a typical dropout voltage of 0.25V at full load. Packaged in a compact 6-DFN (2x2mm) format with an exposed pad, it supports surface-mount installation. The regulator includes integrated protection mechanisms such as overcurrent limiting and thermal shutdown, ensuring reliable operation across an industrial temperature range of -40°C to +85°C.

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

Verify the exact suffix designation when ordering, as manufacturer integration may have updated nomenclature standards. Confirm that the 6-DFN package variant matches your board footprint requirements. Ensure compatibility with the specified 1V output level for your target circuit design. Check for any specific handling instructions related to the exposed thermal pad during assembly processes.

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

Select this component when a precise 1V rail is required from a 2.7V to 5.5V source. Consider its 180mA current capability against your system's peak demand. Evaluate the thermal performance given the small DFN package size under continuous load conditions. Compare its dropout characteristics against other LDOs if input voltage headroom is limited in your design architecture.
