Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status prior to integration. Check datasheet revisions for any pinout or electrical characteristic updates. Ensure proper ESD handling procedures during assembly due to the fine-pitch WLCSP package. Validate supply chain documentation against official Renesas part numbers.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from a 1.8V to 5.5V input source. Consider the 800mA current limit for load requirements. The small WLCSP footprint is ideal for dense PCB layouts. Evaluate thermal performance within the specified operating temperature range. Compare against alternative topologies if variable output voltages are needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9110 series of synchronous buck-boost regulators. It shares architectural similarities with other members like the ISL9112 but differs in output configuration and package type.
