Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix JZ against the manufacturer datasheet to confirm the exact tape-and-reel quantity and packaging specifications. Ensure the fixed 2.8V output variant matches the system requirements, as other suffixes may provide different voltages or packages. Confirm RoHS compliance status directly from the official documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.8V rail is required for low-power logic circuits. The 4.3MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 500mA load capability meets the peak demand of the target application. Consider the thermal performance of the 6-UTDFN package under continuous load conditions.
