S-1701U1815-M5T1G

Overview

The S-1701U1815-M5T1G is a dual-output low-dropout regulator from the ABLIC S-1701 series, housed in an SOT-23-5 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 operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 340 mV at full load. It features a low quiescent current of 85 µA and high voltage regulation accuracy of 1%. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates two independent LDO channels for simultaneous multi-rail power generation
• Combines voltage regulation with integrated voltage detection capabilities
• Maintains stable performance under varying load conditions with low quiescent current consumption

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-powered systems needing efficient power management
• Embedded circuits utilizing combined regulation and monitoring functions

Procurement Notes

Verify the specific suffix M5T1G against official ABLIC documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure the selected variant matches the required thermal dissipation limits for your PCB layout. Cross-reference the datasheet revision history to account for any recent manufacturing changes or parameter updates before finalizing procurement orders.

Selection Notes

Select this component when a compact dual-output solution is required for space-constrained designs. The SOT-23-5 package offers a small footprint suitable for dense layouts. Consider the 340 mV dropout characteristic to ensure sufficient headroom between input and output voltages during operation. Verify that the 400 mA current rating meets the peak demands of both connected loads simultaneously.

Part Context

This part belongs to the S-1701 family of combo voltage detectors and regulators manufactured by ABLIC Inc. The series is designed for applications requiring integrated power management and supervision in a minimal footprint. The S-1701U1815 variant specifically targets systems needing 1.5 V and 1.8 V outputs, distinguishing it from other models in the lineup with different voltage combinations.

Replacement Considerations

Direct substitutes include other S-1701 series parts with identical SOT-23-5 packaging and compatible electrical characteristics. Verify that alternative models match the 1.5 V and 1.8 V output requirements and maintain similar dropout and current specifications. Consult official cross-reference lists for confirmed equivalent part numbers.
