S-1701B1823-M5T1G

Overview

The S-1701B1823-M5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, designed for applications requiring combined voltage regulation and detection. It features two fixed output voltages of 1.8 V and 2.3 V, delivering a maximum output current of 400 mA per channel. The device operates with an input voltage range of 2 V to 6.5 V and maintains a typical quiescent current of 85 µA. Packaged in a compact SOT-23-5 surface-mount format, it supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a line regulation of 0.2%/V and a load regulation of 40 mV, ensuring stable performance under varying conditions.

Feature Summary

• Integrates dual LDO regulators with a built-in voltage detector function within a single package
• Maintains ultra-low power consumption through an 85 µA quiescent current specification
• Provides high precision with a 1% voltage regulation accuracy for stable system operation

Applications

• Portable electronic devices requiring efficient multi-rail power management
• Battery-powered systems needing extended operational life via low standby current
• Embedded circuits utilizing voltage monitoring for system integrity checks

Procurement Notes

Verify the specific suffix M5T1G corresponds to the SOT-23-5 package and reel packaging configuration required for your assembly process. Confirm that the 1.8 V and 2.3 V output combination aligns with your circuit design needs. Ensure compliance with RoHS directives as indicated in official documentation before finalizing procurement orders.

Selection Notes

Select this component when a dual-output solution with integrated voltage detection is necessary to save board space. The SOT-23-5 package offers a compact footprint suitable for dense layouts. Consider the 400 mA output capability and 85 µA quiescent current to balance performance with power efficiency requirements in portable or battery-operated designs.

Part Context

This part belongs to the ABLIC S-1701 series, which specializes in low-power LDO regulators with voltage detector functions. The series is engineered for mobile and portable electronics where power conservation and precise voltage monitoring are critical. The S-1701B1823 variant specifically provides the 1.8 V and 2.3 V output combination, distinguishing it from other models in the family with different voltage pairs.

Replacement Considerations

Check for other S-1701 series parts with identical SOT-23-5 packaging and matching 1.8 V/2.3 V outputs. Verify pin compatibility and thermal characteristics if substituting with similar dual-output LDOs from other manufacturers.
