S-1701F5040-M5T1G

Overview

The S-1701F5040-M5T1G is a low-dropout regulator from ABLIC's S-1701 series, featuring an integrated voltage detector. It provides two fixed output voltages of 4.0 V and 5 V with a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 140 mV. It consumes a quiescent current of 85 µA and offers high accuracy with a line regulation of 0.2 %/V and load regulation of 40 mV. The unit is housed in a compact SOT-23-5 package and supports operation temperatures from -40 °C to +85 °C.

Feature Summary

• Combines dual-output LDO regulation with a voltage detection function in a single component
• Provides fixed 4.0 V and 5 V outputs with 400 mA continuous current capability
• Features ultra-low quiescent current consumption for extended battery life
• Ensures stable performance with low dropout voltage and high precision regulation

Applications

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

Procurement Notes

Verify the specific output voltage combination (4.0 V and 5 V) matches the design requirements before ordering. Confirm the SOT-23-5 package footprint aligns with the PCB layout. Ensure the operating temperature range meets the environmental conditions of the target application. Check for RoHS compliance documentation if required by regulatory standards.

Selection Notes

Select this component when a combined regulator and voltage detector solution is needed to save board space. The 400 mA output current supports moderate load demands. Consider the 140 mV dropout voltage relative to the minimum input voltage available in the system. The fixed output configuration simplifies design compared to adjustable regulators.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators manufactured by ABLIC Inc. The series is designed for portable equipment, offering high integration and low power consumption. The S-1701F5040-M5T1G specifically denotes the fixed output variant with 4.0 V and 5 V rails in the SOT-23-5 package.

Replacement Considerations

Direct substitutes may include other parts from the S-1701 series with different output voltages or packages, such as S-1701F5041-M5T1G or S-1701D5043-M5T1G, provided the electrical specifications and pinout compatibility are verified.
