Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DZ' against official Renesas documentation to confirm package type and tape/reel specifications. Confirm availability status as discontinuation notices may apply to this series. Ensure compatibility with RoHS3 standards if required by the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 2V output is required for 500mA loads. The 4.3MHz frequency suits space-constrained designs needing smaller inductors. Compare against adjustable variants like ISL9104AIRUAZ-T if flexible output voltages are needed instead of a fixed rail.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the ISL9104 family of synchronous buck converters. It shares core topology and control logic with other members but differs in output configuration. While some variants offer adjustable outputs, this specific model provides a fixed voltage level optimized for standard logic supply requirements.
