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

This component is officially classified as obsolete and no longer in production by Fairchild Semiconductor. Verify availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing PCB footprints and thermal requirements when sourcing replacements. Confirm authenticity due to potential counterfeit risks associated with discontinued parts.

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

Select this part only if a fixed 3.15V output is strictly required and the system can accommodate obsolete components. Consider the low dropout characteristic for applications where input voltage closely approaches the output level. Evaluate alternative active LDO regulators if long-term supply chain stability is critical for the product lifecycle.

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

The FAN2502 series represents a family of micropower low-dropout regulators designed for cost-effective performance in portable applications. The FAN2502S315X specifically denotes the fixed 3.15V variant within this lineup. Fairchild Semiconductor was acquired by ON Semiconductor in September 2016, which now manages the legacy product portfolio.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must identify equivalent LDO regulators with matching 3.15V output, 150mA current rating, and SOT-23-5 package manually.
