Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number ISL9111EH33Z-T7A against official Renesas documentation to confirm the specific 3V fixed output variant. Ensure compatibility with the required 0.8V to 2.8V input range and 800mA current capability for your design. Confirm RoHS3 compliance and standard lead-free status prior to integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3V output is required from low-voltage sources between 0.8V and 2.8V. The 800mA switch current limit defines the maximum deliverable load capacity. Consider the 1.2MHz frequency for balancing component size and efficiency. The SOT-23-6 package dictates the physical footprint constraints on the PCB layout.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9111 family of high-efficiency synchronous boost regulators. The 'H33' suffix specifically denotes the fixed 3.0V output version, distinguishing it from adjustable or other fixed voltage variants within the same series. It shares core topology and control features with other members like the ISL9111EHADJZ-T7A.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other ISL9111 family members with matching electrical characteristics, such as ISL9111EH30Z-T7A (3.0V) or ISL9111EHADJZ-T7A (Adjustable), provided the output voltage requirement aligns. Verify pinout and thermal performance similarities before substitution.
