Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix KR-G against the manufacturer's official datasheet to confirm the MSOP-8 package type and tape-and-reel packaging details. Ensure that the required output voltage of 5.1 V matches the design specifications, as this parameter is fixed by the part number. Cross-reference the RoHS compliance status directly with the supplier documentation prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.1 V output is required from an input source ranging between 1.8 V and 5.5 V. The MSOP-8 package is suitable for space-constrained designs. Consider the 80 mA output current limit and 300 kHz switching frequency when designing external passive components. Verify thermal performance within the -40°C to +85°C operating range for the intended application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9801 series of regulated voltage step-up charge pump ICs from Torex Semiconductor. The series offers various fixed output voltage options, distinguished by the middle digits in the part number (e.g., B503 for 5.0 V, B333 for 3.3 V).
