S-1701D1817-M5T1G

Overview

The ABLIC S-1701D1817-M5T1G is a dual-output low dropout (LDO) voltage regulator featuring integrated voltage detection capabilities. It provides fixed output voltages of 1.7 V and 1.8 V with a maximum output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V, ensuring stable regulation under varying supply conditions. It maintains a typical quiescent current of 85 µA, supporting energy-efficient operation in battery-powered applications. The unit delivers high ripple rejection and includes reset functions for system reliability.

Feature Summary

• Dual fixed output channels providing independent regulated voltages
• Integrated voltage detector with reset function for system monitoring
• Ultra-low quiescent current consumption for extended battery life
• High ripple rejection ratio for clean power delivery

Applications

• Battery-operated portable electronic devices requiring multiple voltage rails
• Embedded systems needing reliable voltage supervision and reset signals
• Low-power consumer electronics with strict standby current constraints
• Industrial control modules utilizing dual voltage supplies for logic and peripherals

Procurement Notes

Verify the specific suffix M5T1G corresponds to the SOT-23-5 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure input voltage specifications align with your system's power source limits to prevent damage. Check for any recent product change notifications that may affect pinout or electrical characteristics.

Selection Notes

Select this component when dual isolated outputs are required from a single LDO structure. The 400 mA output capability supports moderate load currents for digital logic and peripheral interfaces. Consider the SOT-23-5 package size if board space is limited compared to larger SOT-89 variants. Evaluate the 85 µA quiescent current against total system power budgets for optimal efficiency.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. The series is designed for applications requiring both power regulation and voltage monitoring in a compact footprint. It complements other S-1701 variants that offer different output voltage combinations or package options like SOT-89-5.

Replacement Considerations

Check for direct substitutes within the S-1701 family offering identical 1.7 V and 1.8 V outputs. Verify pin compatibility with existing PCB layouts when considering alternative packages such as SOT-89-5 versions. Ensure thermal performance meets requirements if operating near maximum current limits.
