S-1701V5043-M5T1G

Overview

The S-1701V5043-M5T1G is a dual-output low-dropout regulator and voltage detector by ABLIC. It provides fixed outputs of 4 V and 5 V with a maximum output current of 400 mA. The device features an ultra-low quiescent current of 85 uA. It operates within an input voltage range of 2 V to 6.5 V and supports surface-mount installation in an SOT-23-5 package. The unit maintains a typical dropout voltage of 140 mV, with a maximum of 210 mV at 100 mA. Line regulation is specified at 0.2 %/V, and load regulation is 40 mV. Power dissipation reaches 420 mW. The component functions reliably across a temperature range of -40 C to +85 C.

Feature Summary

• Integrates dual fixed-voltage LDO regulators with a combined voltage detection function for system monitoring.
• Achieves ultra-low power consumption through an 85 uA quiescent current specification suitable for battery-powered applications.
• Delivers high drive capability with a 400 mA output current while maintaining stable regulation under varying loads.

Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing extended operational life
• Embedded circuits requiring simultaneous voltage regulation and supply monitoring

Procurement Notes

Verify the specific suffix M5T1G against official ABLIC documentation to confirm the exact pin configuration and tape-and-reel specifications. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the part number with the latest datasheet revision to confirm compliance with RoHS standards and environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a single package solution for both power regulation and voltage supervision is required. The dual output configuration allows for generating multiple logic levels from a single input source. Consider the 400 mA current limit and thermal dissipation capabilities relative to the expected load profile. Verify that the input voltage range accommodates the minimum operating voltage of the target application.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed to replace separate regulator and monitor ICs, reducing board space. The S-1701V5043 variant specifically targets applications needing 4 V and 5 V rails. It utilizes ABLIC's CMOS technology to ensure high reliability and low noise performance in compact form factors.

Replacement Considerations

Direct substitutes include other S-1701 series variants with compatible output voltages and packages, such as S-1701D5043-M5T1G or S-1701F5043-M5T1G. Verify pin compatibility and thermal characteristics before substitution. Generic LDO replacements may lack the integrated voltage detection feature.
