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

Verify the specific suffix 'X' against official Fairchild documentation to confirm tape-and-reel packaging or specific marking variations. Ensure the orderable part number matches the exact electrical specifications required for your design, as suffixes may indicate package type or environmental compliance status. Cross-reference the manufacturer's current datasheet to confirm availability and any potential obsolescence notices prior to procurement.

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

Select this component when dual isolated low-noise outputs are required from a single package. The 150mA per channel rating suits moderate load currents in RF front-ends. Consider the 0.155V typical dropout for headroom calculations. Verify that the 10V absolute maximum input rating aligns with the system supply voltage. The MSOP/VSSOP/TSSOP8 footprint must fit the PCB layout constraints.

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

This part belongs to the ILC7280 series of micropower dual LDO regulators. It is categorized under power management ICs, specifically linear regulators. The series is designed for applications requiring low quiescent current and low noise performance, distinguishing it from standard high-current LDOs. Fairchild Semiconductor (now ON Semiconductor) produced this family for consumer and communication electronics.

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

Consult official Fairchild/ON Semiconductor substitution guides for direct pin-compatible alternatives. Generic equivalents may not match the specific RF noise characteristics or dual-channel isolation of the ILC7280. Verify thermal performance and package dimensions if considering third-party replacements.
