S-1701E5040-M5T1G

Overview

The S-1701E5040-M5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, designed for automotive and industrial applications. It integrates a fixed voltage regulator and a voltage detector in a single package. The device provides a regulated output of 4.0 V with a maximum load current of 400 mA, while the integrated voltage detector monitors the input supply. Key electrical specifications include an ultra-low quiescent current of 85 µA, a typical dropout voltage of 140 mV at 100 mA, and a line regulation of 0.2 %/V. The component operates within an input voltage range of 2.0 V to 6.5 V and supports a power dissipation of up to 420 mW in its SOT-23-5 surface-mount package.

Feature Summary

• Integrates a fixed-output LDO regulator and a voltage detector function within a single compact package
• Features ultra-low quiescent current consumption to minimize standby power loss
• Provides stable voltage regulation with low dropout characteristics under varying load conditions
• Designed for high reliability with operation across extended industrial temperature ranges

Applications

• Automotive electronic control units requiring combined regulation and monitoring
• Industrial equipment power management systems
• Battery-powered devices needing efficient voltage conversion and supply monitoring
• Embedded systems utilizing microcontrollers with integrated watchdog or reset requirements

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal ratings. Ensure the ordering quantity aligns with manufacturer reel sizes, typically 3000 units for this package type. Confirm RoHS compliance status and check for any recent product change notifications that may affect mechanical dimensions or material composition before finalizing procurement plans.

Selection Notes

Select this component when a design requires both precise voltage regulation and input supply monitoring without consuming additional board space. The 400 mA output current capability suits moderate load applications, while the 85 µA quiescent current ensures efficiency in battery-operated scenarios. Verify that the required output voltage of 4.0 V matches the system logic levels and that the input voltage range covers the expected supply variations during operation.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators manufactured by ABLIC Inc. The series is characterized by its integration of linear regulation and detection functions, targeting applications where space constraints and power efficiency are critical. The S-1701 family offers various output voltage combinations and package options, including SOT-23-5 and SOT-89-5, to accommodate different thermal and form-factor requirements in modern electronic designs.

Replacement Considerations

Direct substitutes within the S-1701 series include variants with different output voltages but identical pinouts, such as S-1701E5042-M5T1G. Cross-manufacturer replacements require careful verification of pin compatibility, dropout voltage characteristics, and quiescent current specifications to ensure functional equivalence in the existing circuit layout.
