S-1701Q1515-M5T1G

Overview

The S-1701Q1515-M5T1G is a dual-output low dropout (LDO) voltage regulator from ABLIC, featuring integrated voltage detection capabilities. It provides two fixed output voltages of 1.5 V each, with a maximum continuous output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical quiescent current of 85 µA. It exhibits a maximum dropout voltage of 580 mV at 100 mA load and offers a voltage regulation accuracy of 1%. The unit is housed in a compact SOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel linear regulation with integrated voltage detector functionality
• Ultra-low quiescent current consumption for extended battery life
• High precision voltage regulation with 1% accuracy tolerance
• Compact SOT-23-5 surface-mount packaging for space-constrained designs

Applications

• Portable consumer electronics requiring efficient power management
• Battery-powered devices needing low standby current
• Embedded systems utilizing multiple fixed voltage rails
• IoT modules requiring compact power solutions

Procurement Notes

Verify the specific suffix M5T1G corresponds to the required reel quantity and tape specifications during ordering. Confirm that the fixed 1.5 V dual output aligns with system requirements, as alternative voltage combinations exist within the S-1701 series. Ensure thermal design accounts for the 420 mW power dissipation limit under maximum load conditions. Check RoHS compliance documentation for regional regulatory adherence before final procurement approval.

Selection Notes

Select this component when a dual 1.5 V supply is required alongside minimal quiescent current draw. The 400 mA output capability suits moderate load applications, while the 2 V minimum input voltage allows operation from single-cell lithium batteries. Consider the S-1701N or S-1701D variants if different output voltage combinations are needed. The SOT-23-5 package is suitable for high-density PCB layouts where space is limited compared to larger regulator packages.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators manufactured by ABLIC Inc. The series integrates LDO regulation with voltage monitoring functions in a single chip. The S-1701Q variant specifically denotes the dual 1.5 V output configuration. This family targets applications requiring efficient power conversion with built-in supervision features in ultra-compact packages.

Replacement Considerations

S-1701N3315-M5T1G offers identical electrical characteristics but provides 1.5 V and 3.3 V outputs instead of dual 1.5 V. S-1701D5043-M5T1G provides 4.3 V and 5 V outputs with the same package and current ratings. Verify pinout compatibility and thermal performance when substituting these variants.
