Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '24' corresponds to the 3.5V fixed output variant when sourcing. Confirm the package designation matches the 6-USPEL footprint requirements for your PCB layout. Ensure compatibility with the required operating temperature range for your specific application environment before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.5V output is required from inputs as low as 0.9V. The synchronous design offers better efficiency than non-synchronous alternatives at similar current levels. Consider the small 6-USPEL package size if board space is constrained. Verify that the 100mA output capability meets the peak load demands of the target circuit.
