Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'RTAZ' corresponds to the TQFN-EP-20 package variant when ordering. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference pinouts with the latest Renesas release notes to avoid assembly errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring wide input voltage flexibility without inverting polarity. The 2.5 MHz frequency optimizes the trade-off between efficiency and passive component size. Evaluate thermal dissipation requirements based on the TQFN-EP-20 footprint and expected load currents. Ensure input capacitor ratings exceed the maximum operating voltage of 5.5 V.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL91107 series of high-efficiency buck-boost regulators from Renesas. It shares functional similarities with other members like the ISL91107IIAZ but differs in packaging and pinout configuration. The series targets applications needing reliable power management from single-cell sources.
