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

Verify the specific suffix 'S' corresponds to the TO263 package variant required for your layout. Confirm RoHS compliance status matches project environmental standards. Check datasheet revision history for any updates to electrical characteristics or pin assignments before finalizing procurement orders.

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

Select this component when a fixed 3.3V rail is needed with up to 1A load current. Ensure the input voltage does not exceed 15V. Consider the thermal resistance of the TO263 package for heat dissipation requirements. Verify that the dropout voltage meets the minimum headroom constraints of the application circuit.

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

This part belongs to the AZ1117 series of three-terminal low dropout regulators. The series offers various fixed voltage options and an adjustable version across multiple package types including SOT223, SOT89, and TO252. The AZ1117S specifically utilizes the TO263 package for higher thermal performance compared to smaller surface-mount options.

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

Datasheet explicitly recommends using AZ1117C or AZ1117I series parts instead of the standard AZ1117 for new designs due to obsolescence notices. No direct substitute part numbers are provided in the documentation.
