S-1701Q5015-U5T1G

Overview

The S-1701Q5015-U5T1G is a dual-output low dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides fixed output voltages of 1.5 V and 5.0 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and operates within an input voltage range supporting these outputs. It utilizes an SOT-89-5 surface-mount package and maintains operation across a temperature range from -40°C to +85°C. This component integrates voltage detection capabilities alongside regulation functions.

Feature Summary

• Integrates dual fixed voltage regulators with combined voltage detection functionality
• Provides high output current capability of 400 mA for load applications
• Maintains low power consumption with minimal quiescent current draw during operation

Applications

• Power supply circuits in portable electronic devices requiring multiple voltage rails
• Embedded systems utilizing microcontrollers needing stable logic and peripheral voltages
• Battery-powered equipment where efficient power management and extended runtime are critical

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required tape-and-reel packaging configuration and quantity. Confirm that the SOT-89-5 pinout matches the target PCB footprint design. Ensure the thermal dissipation requirements align with the expected ambient operating conditions and board layout constraints for reliable performance.

Selection Notes

Select this component when a single package solution is needed for generating both low-voltage logic levels and higher-voltage rail supplies simultaneously. Consider the 400 mA output capacity against peak load demands. Evaluate the dropout voltage characteristics relative to the minimum input voltage available in the system architecture to ensure stable regulation under all operating conditions.
