S-1701R2515-U5T1G

Overview

The ABLIC S-1701R2515-U5T1G is a dual-output low dropout (LDO) voltage regulator featuring integrated voltage detection capabilities. It provides fixed output voltages of 1.5 V and 2.5 V with a maximum output current of 400 mA per channel. The device operates within an input voltage range of 1.8 V to 6.5 V, ensuring stable regulation under varying supply conditions. Key electrical specifications include a typical quiescent current of 85 µA and a maximum dropout voltage of 340 mV at full load. The unit maintains a voltage regulation accuracy of ±1% and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 package and reel packaging configuration required for your assembly line. Confirm that the 1.5 V and 2.5 V output combination matches your schematic design, as other variants in the S-1701 series offer different voltage pairs. Ensure compliance with RoHS directives and check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a single IC solution is needed to generate two distinct positive voltages while minimizing board space. The S-1701R2515-U5T1G is suitable for designs where low standby current is critical, such as always-on memory or microcontroller backup supplies. Consider the SOT-89-5 package for its thermal performance relative to smaller footprints if higher power dissipation is anticipated. Verify that the input voltage remains above the sum of the highest output voltage and the dropout voltage for proper regulation.

Part Context

This part belongs to the ABLIC S-1701 series, which combines LDO regulators with voltage detectors in a compact form factor. The series is designed for high-reliability applications in consumer electronics and automotive sectors. The 'R' designation typically indicates the inclusion of the voltage detection function alongside the regulation outputs. This specific model offers a common industry-standard voltage pair for logic and peripheral interfaces.

Replacement Considerations

Direct replacements must match the dual-output configuration (1.5 V/2.5 V), 400 mA current rating, and SOT-89-5 package. Check datasheets for equivalent quiescent current and dropout voltage specifications to ensure circuit stability. Verify that substitute parts also include the voltage detector feature if system reset functionality is required.
