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

Verify the specific suffix designation against the original design requirements, as package variations exist within the CA3085 family. Confirm that the die form factor aligns with the intended assembly process. Ensure compatibility with the thermal management strategy required for the application environment. Cross-reference the manufacturer lot codes to verify authenticity and traceability standards.

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

Select this component when an adjustable positive regulator with a 1.6V to 27V range is required. Consider the bipolar technology characteristics for noise and stability performance. Evaluate the mechanical constraints if integrating the die directly into a substrate. Compare against other adjustable regulators if surface-mount packages are strictly mandated by the PCB layout.

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

Rochester Electronics specializes in the sourcing and production of obsolete and lifecycle-discontinued semiconductors. The CA3085 series originates from earlier industry standards for linear voltage regulation. This part ensures continuity for designs originally specified by manufacturers such as Harris or RCA, bridging the gap between legacy hardware and current supply chain realities.

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

Direct pin-compatible replacements may include variants like CA3085H or CA3085T depending on the required package type. Verify electrical specifications match exactly before substitution. Other adjustable regulators from different families may require schematic modifications.
