Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'ZELT15' to confirm the 1.5 V fixed output specification, as other variants exist within the MAX8640 family. Ensure compatibility with the SC-70-6 footprint during PCB layout. Confirm RoHS compliance status through official documentation before integration into production environments.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.5 V output is required from a 2.7 V to 5.5 V input source. The 3.9 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 500 mA current limit for load requirements and ensure thermal management suits the SC-70-6 package size.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX8640 series of tiny, high-efficiency synchronous step-down converters. It is designed for applications where board space is limited and power efficiency is critical.
