Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized channels due to market prevalence of counterfeits. Confirm RoHS compliance status and specific tape-and-reel quantities against current distributor listings. Check for recent Product Change Notifications regarding packaging or manufacturing site updates before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for 5V systems needing up to 1A output. The fixed high-frequency operation reduces inductor size compared to lower-frequency alternatives. Ensure the application load does not exceed the 1A continuous rating and that the input voltage remains within the specified 2.7V to 5.5V window.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the EL7536/ISL97536 family of 1A step-down regulators. It shares functional similarities with the EL7536IYZ but may differ in specific pinout configurations or thermal characteristics depending on the exact datasheet revision. It serves as a direct replacement for older Intersil variants in existing designs requiring synchronous buck topology.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations
