S-1701D1815-M5T1G

Overview

The S-1701D1815-M5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, manufactured by ABLIC Inc. It provides fixed output voltages of 1.5 V and 1.8 V with a maximum output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V and features a typical quiescent current of 85 µA. Packaged in a compact SOT-23-5 surface-mount format, it supports operation across a temperature range of -40°C to +85°C. Key electrical characteristics include a line regulation of 0.2%/V and a load regulation of 40 mV.

Feature Summary

• Integrates two independent LDO regulators with a combined voltage detector function for system monitoring.
• Maintains stable performance with ultra-low quiescent current consumption suitable for battery-powered applications.
• Provides high precision voltage regulation with a tight accuracy tolerance of 1%.

Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing multiple regulated voltage rails
• Battery-operated equipment prioritizing low standby current

Procurement Notes

Verify the specific suffix M5T1G to confirm the SOT-23-5 package configuration and reel packaging quantity. Ensure compatibility with standard surface-mount assembly processes. Cross-reference the manufacturer part number against official distributor catalogs to confirm availability and lead times. Validate that the operating temperature range meets your environmental requirements before finalizing procurement.

Selection Notes

Select this component when a dual-output solution is required to save board space compared to using separate single regulators. The SOT-23-5 package offers a smaller footprint than larger alternatives like SOT-89. Consider the 400 mA current limit and 1.5 V/1.8 V output levels to ensure they match the load requirements of your target circuit design.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed to provide both power regulation and voltage monitoring functions in a single integrated circuit. This specific model utilizes the M5 suffix designation, which corresponds to the SOT-23-5 package type, distinguishing it from other variants in the family that may use different housing styles.

Replacement Considerations

Compatible substitutes within the same series include S-1701Q1515-M5T1G and S-1701N3315-M5T1G. These parts share identical pinouts and package dimensions but offer different fixed output voltage combinations. Verify that the alternative voltage levels align with your system's power distribution requirements before substitution.
