S-1701R1515-U5T1G

Overview

The S-1701R1515-U5T1G is a dual-output low dropout regulator from ABLIC's S-1701 series, housed in an SOT-89-5 surface-mount package. 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 a temperature range of -40°C to +85°C. It includes integrated voltage detection functionality alongside regulation.

Feature Summary

• Dual independent fixed voltage outputs for simultaneous power rail generation
• Ultra-low standby current consumption suitable for battery-powered applications
• Integrated voltage detector circuit for system supervision
• Compact SOT-89-5 package design for space-constrained PCB layouts

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-operated systems needing extended standby life
• Embedded controllers requiring integrated power management and supervision
• Industrial control modules operating in wide temperature environments

Procurement Notes

Verify the specific output voltage configuration matches the target application requirements before ordering. Confirm that the SOT-89-5 thermal characteristics are sufficient for the expected load conditions. Ensure compatibility with existing board footprints and soldering profiles. Check for any recent product change notifications regarding pinout or electrical specifications.

Selection Notes

Select this component when dual regulated outputs are required from a single package to save board space. Consider the 85 µA quiescent current for efficiency-critical designs. Evaluate the dropout voltage specifications against the minimum input voltage available in the system. Verify that the 400 mA current rating meets the peak load demands of both output channels simultaneously.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators designed by ABLIC. The series focuses on providing integrated power management solutions with low standby current. The S-1701R1515 variant specifically offers 1.5 V and 1.8 V outputs, catering to digital logic and peripheral power needs in compact mobile and industrial applications.

Replacement Considerations

Check for direct cross-reference parts within the S-1701 family offering different voltage combinations. Verify pin-to-pin compatibility if substituting with other LDO manufacturers. Ensure equivalent quiescent current and dropout voltage performance metrics are maintained.
