S-1701R1815-U5T1G

Overview

The S-1701R1815-U5T1G is a dual-output low dropout regulator from the ABLIC S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed positive output voltages of 1.5 V and 1.8 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 340 mV. It operates within a temperature range of -40°C to +85°C and includes built-in overcurrent protection and thermal shutdown circuits for enhanced reliability.

Feature Summary

• Dual independent fixed voltage outputs integrated into a single compact component
• Ultra-low quiescent current consumption designed for battery-powered applications
• Integrated overcurrent protection and thermal shutdown mechanisms for circuit safety

Applications

• Portable electronic devices requiring multiple stable voltage rails

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required reel packaging quantity and tape specifications before ordering. Confirm that the SOT-89-5 pinout matches your PCB footprint design. Ensure input voltage levels remain within safe operating limits to prevent thermal stress during high-load conditions.

Selection Notes

Select this model when two distinct regulated voltages are needed from a single source without external switching complexity. Compare dropout characteristics against load requirements to ensure regulation stability. Consider the S-1701 series alternatives if different output combinations or package sizes better suit the mechanical constraints of the target assembly.
