S-1701U5040-M5T1G

Overview

The S-1701U5040-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC from ABLIC. It features an input voltage range of 2.0 V to 6.0 V, providing a fixed 4.0 V output with a maximum current of 400 mA. The device incorporates a built-in voltage detector that triggers at 4.0 V. Key electrical characteristics include a quiescent current of 85 µA and a typical dropout voltage of 140 mV at 400 mA. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 package.

Procurement Notes

Verify the specific suffix M5T1G corresponds to the SOT-23-5 package and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure compatibility with your PCB footprint design for the SC-74A/SOT-753 variant. Check for any recent Product Change Notifications affecting pinout or specifications before finalizing procurement orders.

Selection Notes

Select this component when a combined regulator and voltage detector is required in a minimal footprint. The 4.0 V output suits applications needing precise supply monitoring. Consider the 85 µA quiescent current for battery life optimization. Verify input voltage ranges meet system requirements. Compare against other S-1701 series variants if different output voltages are needed.
