Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the WSON-10 package variant matches the design requirements. Ensure the fixed 5.0 V output aligns with the target circuit load. Cross-reference the 1.7 MHz switching frequency against EMI constraints. Validate the operating temperature range against environmental conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when inductor-less solutions are required for boosting voltages from single-cell lithium batteries or similar sources. Consider the 120 mA current limit for moderate load demands. Evaluate the 1.7 MHz frequency for trade-offs between component size and electromagnetic interference. Compare thermal performance in the WSON package against alternative regulators for the specific application environment.
