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

Verify the specific manufacturer origin as documentation references both Fairchild Semiconductor and onsemi due to corporate acquisitions. Confirm the exact suffix 'X' denotes the correct tape and reel packaging variant if required for automated assembly. Ensure compliance with RoHS directives as indicated in available datasheets. Cross-reference the part number against current onsemi catalogs to confirm availability status and any potential obsolescence notices before finalizing procurement plans.

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

Select this component when dual isolated low-noise supplies are needed from a single input source. The 150mA output current capability suits moderate load requirements. Consider the wide operating temperature range (-65°C to +150°C) for harsh environment applications. The small MSOP-8 package is ideal for space-constrained PCB designs. Verify that the input voltage remains within the 10V absolute maximum limit during all operational transients.

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

This device belongs to the ILC7280 series of micropower dual LDO regulators. It shares functional similarities with other parts in the family but differs in specific output voltage configurations and packaging options. The series is characterized by its CMOS construction, which enables lower quiescent current compared to bipolar counterparts. It serves as a legacy component from Fairchild's portfolio, now managed under onsemi's product line.

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

Check for direct equivalents in the ILC7280 series with matching output voltages. Verify pin compatibility with alternative dual LDOs in MSOP-8 packages. Ensure replacement components meet the same RF noise and dropout voltage specifications.
