Procurement Notes

Verify the exact part number suffix against official ABLIC documentation to ensure correct output voltage and package configuration. Confirm RoHS compliance status through the manufacturer's latest datasheet or product change notifications. Check for any specific handling requirements during storage and assembly. Ensure compatibility with your PCB footprint design, specifically the SOT-23-5 pinout. Validate that the operating temperature range meets your application's environmental specifications before finalizing procurement.

Selection Notes

Select this component when a combined voltage regulation and detection function is required in a compact form factor. Consider its 400 mA output current capacity for moderate load applications. Evaluate the 85 µA quiescent current against battery life requirements. Compare the 140 mV dropout voltage with your minimum input voltage constraints. Ensure the SOT-23-5 package fits your board layout constraints compared to other available packages in the S-1701 series.

Part Context

The S-1701U5041-M5T1G belongs to the S-1701 series of LDO regulators from ABLIC Inc. This series is characterized by low quiescent current and integrated voltage detectors. The 'U' suffix typically denotes specific package or tape/reel configurations, while 'M5T1G' indicates the SOT-23-5 package and lead-free composition. Other variants in the series offer different output voltages and package options to suit diverse design needs.

Replacement Considerations
