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

Verify the manufacturer designation as Fairchild Semiconductor or its successor entities during sourcing. Confirm the complete part number matches ILC7082AIM533X exactly, noting that suffix variations may indicate different tape-and-reel quantities or packaging options rather than functional changes. Ensure RoHS compliance status aligns with project requirements. Cross-reference datasheet revisions to confirm electrical characteristics remain consistent with design specifications.

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

Select this component when a fixed 3.3V rail is required with moderate current demands up to 150mA. Consider the low dropout characteristic for applications where input voltage closely approaches the output level. Evaluate the 220µA quiescent current against system power budgets. Verify that the 8-SOIC package fits within the available PCB footprint constraints. Ensure the operating temperature range meets environmental conditions.

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

This device belongs to the ILC708x series of low-dropout regulators designed for general-purpose voltage regulation. The ILC7082 variant specifically provides a fixed 3.3V output, distinguishing it from adjustable versions like the ILC7084. It shares common family features such as thermal protection and enable control but differs in output voltage configuration. The series targets applications requiring simple, reliable linear regulation without external feedback components.
