S-1701T1815-U5T1G

Overview

The S-1701T1815-U5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, manufactured by ABLIC Inc. It provides fixed 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 operates within an input voltage range of 2 V to 6.5 V. It utilizes an SOT-89-5 surface-mount package and supports an operating temperature range from -40°C to +85°C. The regulator includes integrated voltage detection capabilities alongside regulation functions.

Feature Summary

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required tape-and-reel packaging configuration and lead-free compliance status. Confirm that the SOT-89-5 footprint matches your PCB layout constraints. Ensure the selected variant meets the thermal dissipation requirements for your specific ambient temperature conditions.

Selection Notes

Select this component when dual fixed outputs are required in a compact form factor. Compare dropout voltage specifications against load current requirements to ensure regulation stability. Evaluate the total power dissipation capability relative to the expected voltage drop and load current to prevent thermal shutdown.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is characterized by high precision and low power consumption. Other variants in the family offer different output voltage combinations and package options such as SOT-23-5, catering to diverse space and performance constraints.

Replacement Considerations

Check for other S-1701 series parts with identical output voltages but different packages if pin compatibility is not critical. Verify functional equivalence with other dual-output LDOs regarding enable logic and detector thresholds.
