S-1701C5040-M5T1G

Overview

The S-1701C5040-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC from ABLIC. It features a fixed 5.0V output with a maximum output current of 400mA. The device operates within an input voltage range of 2.0V to 6.0V, maintaining regulation with a typical dropout voltage of 140mV at 400mA. Quiescent current is specified at 85µA. It includes an integrated voltage detector with a reset output function. The component is housed in a compact SOT-23-5 package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Combines LDO regulator and voltage detector functions in a single package
• Low quiescent current consumption for battery-powered applications
• Integrated reset output with delay time control
• Compact SOT-23-5 surface-mount packaging

Applications

• Battery-powered portable devices
• Mobile phone circuits
• Digital camera power management
• Consumer electronics requiring combined regulation and monitoring

Procurement Notes

Verify the specific suffix M5T1G corresponds to the required tape-and-reel quantity and marking configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage requirements align with the 2.0V to 6.0V operational range defined in the datasheet. Validate thermal performance under maximum load conditions within the specified temperature limits.

Selection Notes

Select this component when both regulated power supply and system monitoring are required in space-constrained designs. The 400mA output capability suits moderate load applications. Consider the fixed 5.0V output if compatible with downstream logic levels. Evaluate the 85µA standby current against strict power budget constraints for battery-operated equipment.

Part Context
