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

Verify the component status as the datasheet explicitly states this device is discontinued and not recommended for new design. Confirm availability through authorized distributors or onsemi representatives for existing inventory. Ensure compliance with RoHS standards and check for updated part numbers resulting from Fairchild Semiconductor integration if sourcing replacement stock.

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

Select this component for applications requiring a fixed 1.0V rail with moderate current demands up to 180mA. The MLP-6 package suits space-constrained designs. Verify that the input voltage remains above the minimum requirement of 2.7V. Consider the discontinuation status when planning long-term production runs and evaluate alternative regulators if new design implementation is required.

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

This part belongs to the FAN2558/FAN2559 family of low voltage CMOS LDOs. The FAN2558 series specifically includes a Power Good output, distinguishing it from the FAN2559 which offers low noise bypass capabilities. The MP suffix indicates the 2x2mm MLP-6 package variant, providing a smaller footprint compared to SOT-23 options while maintaining similar electrical performance characteristics.
