S-1701S1815-M5T1G

Overview

The S-1701S1815-M5T1G is a low-dropout voltage regulator and voltage detector combo IC manufactured by ABLIC. It features an ultra-low quiescent current of 85 µA and supports a maximum output current of 400 mA. The device provides two fixed output voltages: 1.5 V and 1.8 V. It operates within a temperature range of -40°C to +85°C and utilizes an SOT-23-5 package.

Feature Summary

• Integrates dual-output LDO regulation with voltage detection functionality in a single compact package
• Maintains ultra-low standby power consumption through minimized quiescent current design
• Delivers stable high-current performance suitable for powering multiple logic domains simultaneously

Applications

• Portable electronic devices requiring efficient multi-voltage rail generation
• Battery-powered systems prioritizing extended operational lifetime
• Embedded circuits needing simultaneous regulated supply and voltage monitoring

Procurement Notes

Verify the specific suffix M5T1G against official ABLIC documentation to confirm tape-and-reel packaging specifications and lead-free compliance status. Ensure the ordering code matches the exact voltage combination requirements, as minor suffix variations may indicate different thermal or packaging configurations not explicitly detailed in general summaries.

Selection Notes

Select this component when both 1.5 V and 1.8 V rails are required from a single source with minimal static power draw. The integrated voltage detector simplifies system supervision compared to using separate regulator and monitor chips. Confirm that the 400 mA output capability aligns with peak load demands while maintaining acceptable dropout voltage margins across the operating temperature range.

Part Context

This part belongs to the S-1701 series, which combines linear regulation with supervisory functions. It targets applications where space constraints and power efficiency are critical. The series distinguishes itself by offering dual outputs in small packages, reducing bill-of-materials complexity for designs requiring multiple low-voltage supplies.

Replacement Considerations

Direct substitutes include other S-1701 variants with matching output voltages, such as S-1701R1815-M5T1G or S-1701T3315-M5T1G, provided the voltage levels align with circuit requirements. Verify pin compatibility and thermal characteristics before substitution.
