Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'KR-G' against official Torex documentation to confirm the MSOP-8 package type and reel packaging quantity. Ensure the 3.9 V output variant matches the design requirement, as this parameter distinguishes it from other XC9801 family members. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.9 V output is required from an input range starting at 1.8 V. The 80 mA output current capability suits moderate load applications. Consider the MSOP-8 package for space-constrained designs. Verify that the 300 kHz switching frequency aligns with electromagnetic interference constraints and inductor selection criteria for the target application.
