S-1701B5040-M5T1G

Overview

The S-1701B5040-M5T1G is a dual-output low-dropout (LDO) voltage regulator and voltage detector from ABLIC. It provides fixed output voltages of 4.0 V and 5.0 V with a maximum output current of 400 mA. The device features a low quiescent current of 85 µA and operates within an input voltage range of 2 V to 6.5 V. It utilizes an SOT-23-5 surface-mount package, supports a power dissipation of 420 mW, and functions across a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates dual fixed LDO regulators with a combined voltage detection function in a single compact package.
• Maintains stable regulation with a low dropout voltage of approximately 140 mV at 100 mA load conditions.
• Optimized for battery-powered applications through ultra-low quiescent current consumption.

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-operated systems needing efficient power management
• Embedded circuits utilizing voltage monitoring for system integrity

Procurement Notes

Verify the specific suffix against official ABLIC documentation to confirm pinout compatibility and electrical tolerances. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm RoHS compliance status directly with the supplier prior to procurement.

Selection Notes

Select this component when dual independent voltage outputs are required alongside voltage supervision. Compare dropout characteristics against load requirements to ensure regulation stability. Evaluate thermal performance within the target enclosure to stay within the 420 mW power dissipation limit.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed for portable equipment, offering high integration by combining linear regulation with voltage monitoring capabilities in small surface-mount packages.

Replacement Considerations

Direct substitutes include other S-1701 variants with matching output voltages and package types. Verify functional equivalence regarding quiescent current and dropout voltage before implementation.
