FAN2559S13X

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

The FAN2559S13X is a low-dropout (LDO) linear voltage regulator manufactured by onsemi, formerly Fairchild Semiconductor. It provides a fixed 1.3V output with a maximum load current of 180mA. The device operates within an input voltage range up to 5.5V and features a typical dropout voltage of 140mV at full load. It includes integrated enable and power-good control functions, along with overcurrent and thermal shutdown protection. The component is housed in a compact 6-DFN package and supports operation from -40°C to +85°C.

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

Verify the specific suffix 'S13X' against official datasheets to confirm the 1.3V fixed output variant. Confirm the manufacturer as onsemi/Fairchild due to corporate acquisition history. Check for end-of-life status or obsolescence notices before finalizing procurement plans. Ensure compatibility with RoHS directives if required by your region.

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

Select this component when a fixed 1.3V rail is needed with moderate current demands up to 180mA. Consider the 6-DFN package for board space optimization. Evaluate the need for enable and power-good signals; if not required, simpler LDOs may suffice. Verify input voltage stability does not exceed the 5.5V absolute maximum rating under all operating conditions.
