S-1701D1816-M5T1G

Overview

The S-1701D1816-M5T1G is a dual-output low dropout voltage regulator from the ABLIC S-1701 series, housed in an SOT-23-5 surface-mount package. It provides fixed output voltages of 1.8 V and 1.6 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 an input voltage range of 2 V to 6.5 V. It maintains a voltage regulation accuracy of 1% and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual independent fixed voltage outputs for simultaneous power rail generation
• Ultra-low quiescent current consumption for battery-powered efficiency
• Integrated voltage detector functionality combined with linear regulation

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-operated systems prioritizing low standby power consumption
• Embedded circuits needing compact dual-regulator solutions

Procurement Notes

Verify the specific pinout configuration and thermal characteristics against the official datasheet before finalizing the PCB layout. Confirm that the required output currents do not exceed the 400 mA limit under maximum ambient temperature conditions. Ensure the input voltage remains within the specified 2 V to 6.5 V range to maintain proper regulation and prevent damage.

Selection Notes

Select this component when a single package solution is needed for two distinct low-voltage rails. The SOT-23-5 footprint offers space savings compared to discrete regulators. Consider the 1.8 V and 1.6 V combination suitability for logic interfaces and sensor supplies. Evaluate the 85 µA quiescent current impact on overall system battery life relative to higher-performance alternatives.

Part Context

This part belongs to the ABLIC S-1701 series of combo voltage detectors and regulators. The series is designed for applications requiring both precise voltage regulation and monitoring capabilities in a minimal footprint. The M5T1G suffix indicates the specific SOT-23-5 packaging and tape-and-reel delivery format used for automated assembly processes.

Replacement Considerations

Check for other S-1701 variants with different output combinations if voltage levels require adjustment. Verify compatibility with alternative dual-LDO packages such as SOT-89-5 if thermal dissipation becomes a constraint in the design.
