Procurement Notes

Verify the specific datasheet version and ordering information directly with Mitsumi Electric Company Ltd or authorized distributors. Confirm that the SOT-23-6 (SOT-26A) package matches your PCB footprint requirements. Ensure compliance with RoHS standards if required by your manufacturing process. Check for any specific handling precautions related to electrostatic discharge during assembly.

Selection Notes

Select this component when designing protection circuits for two-cell lithium-based battery systems requiring integrated LDO regulation. Consider the SOT-23-6 package size constraints and the operating temperature range of -40°C to 85°C. Evaluate the need for overcurrent, overvoltage, and short-circuit protection features inherent to this IC. Verify compatibility with your system's voltage requirements against the fixed positive output specification.
