S-1701D5043-M5T1G

Overview

The ABLIC S-1701D5043-M5T1G is a low-dropout regulator featuring integrated voltage detection, housed in an SOT-23-5 package. It provides fixed outputs of 4.3 V and 5 V with a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 140 mV. It functions reliably across a temperature range of -40°C to +85°C, offering line regulation of 0.2%/V and load regulation of 40 mV.

Feature Summary

• Integrates dual fixed voltage outputs with a dedicated voltage detector function for system monitoring.
• Maintains stable regulation with low dropout characteristics under varying load conditions.
• Designed for surface-mount installation using the compact SOT-23-5 footprint.

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing voltage supervision
• Embedded circuits utilizing multiple regulated voltage rails

Procurement Notes

Verify the specific suffix M5T1G confirms the SOT-23-5 packaging and reel quantity requirements. Confirm RoHS compliance status through official documentation before integration. Ensure input voltage limits are respected to prevent device damage during operation.

Selection Notes

Select this component when dual fixed voltages and voltage detection are required in a single package. The SOT-23-5 form factor suits space-constrained designs. Verify that the 400 mA output capability meets the peak load demands of the target application circuitry.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. The series focuses on combining LDO functionality with monitoring capabilities. The D5043 designation specifically indicates the 4.3 V and 5 V output configuration within this product family.

Replacement Considerations

Check for other S-1701 variants with compatible output voltages if pin-out compatibility is critical. Verify package dimensions against existing PCB footprints before substitution.
