S-1701D1815-U5T1G

Overview

The S-1701D1815-U5T1G is a CMOS low dropout voltage regulator with an integrated reset function, manufactured by ABLIC Inc. It features a fixed 1.8 V output and supports input voltages from 2 V to 6.5 V. The device delivers up to 400 mA output current while maintaining high ripple rejection. It operates within a temperature range of -40°C to +85°C and consumes approximately 85 µA of quiescent current. Packaged in SOT-89-5 for surface mount applications.

Feature Summary

• Integrates a voltage detector with reset output functionality alongside the linear regulator
• Provides high ripple rejection ratio for stable power supply in noisy environments
• Designed specifically for battery-powered devices to maximize operational efficiency

Applications

• Battery-powered portable electronic devices
• Voltage conversion circuits requiring reset monitoring
• Noise-sensitive analog or digital subsystems

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 package variant. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure input voltage limits are respected to prevent device damage during operation.

Selection Notes

Select this component when both regulated power delivery and system reset monitoring are required in a single package. The 400 mA capability suits moderate load applications. Verify thermal dissipation requirements for the SOT-89-5 package under maximum load conditions.

Part Context

This part belongs to the S-1701 series of high ripple-rejection LDOs. It combines power management with supervision functions, distinguishing it from standard regulators. The series targets applications needing compact solutions for battery life extension and system reliability.

Replacement Considerations

Check datasheets for compatible parts like S-1701D1815-U5T1X if package differences are acceptable. Verify pinout compatibility and electrical parameter overlaps before substitution.
