Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'JZ' against the manufacturer's official datasheet to confirm the fixed 2.8V output voltage variant. Ensure the ordering code matches the exact tape-and-reel quantity specified in the current production documentation. Cross-reference the RoHS status and MSL rating with the latest component certification documents prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.8V rail is required from a 2.7V to 6V source. The 4.3MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 500mA load requirement fits within the thermal limits of the 6-UTDFN package for the intended application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9104 family, which includes various output voltage options. The IRUJZ-T designation specifically identifies the 2.8V fixed output version in the UTDFN-6 package.
