Special Purpose Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance when ordering. Confirm the package type matches the design requirements, as this part typically comes in SO-16. Ensure the supplier provides valid traceability documentation. Check for any obsolescence notices from Analog Devices Inc. prior to finalizing procurement plans.

Special Purpose Regulators Selection Notes

Select this component for applications requiring a dedicated controller for Intel Pentium processors. It is suitable for designs needing a 200 kHz switching frequency and an input voltage between 4V and 8V. Consider the 350 uA quiescent current for efficiency calculations. Ensure external components support the required output voltage configuration.

Special Purpose Regulators Part Context

The LTC1430 series includes variants like the LTC1430IGN and LTC1430IS. The IS suffix denotes industrial temperature range operation. These controllers are part of Analog Devices' portfolio for specialized voltage regulation, distinct from general-purpose DC/DC converters. They are engineered for specific processor voltage requirements.

Special Purpose Regulators Replacement Considerations

Direct substitutes may include other Intel Pentium voltage regulators from Analog Devices. Verify pin compatibility and electrical specifications before substitution. No direct public substitute part numbers are confirmed in the provided data.
