S-1701A5041-M5T1G

Overview

The S-1701A5041-M5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, designed for automotive and industrial applications. It provides fixed output voltages of 4.1 V and 5.0 V with a maximum output current of 400 mA per channel. The device features an ultra-low quiescent current of 85 µA, ensuring efficient power management in battery-operated systems. It operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 140 mV at 100 mA. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates two independent fixed-voltage LDO regulators with a combined voltage detector function in a single package.
• Achieves ultra-low standby current consumption of 85 µA to extend battery life in portable and automotive electronics.
• Provides stable regulation with a low dropout voltage of 140 mV (typical) under load conditions.
• Includes built-in protection circuits against overcurrent, thermal shutdown, and reverse polarity to ensure system reliability.

Applications

• Automotive infotainment systems requiring multiple regulated voltage rails.
• Engine control units (ECUs) and body control modules needing reliable power sequencing.
• Portable medical devices and handheld instruments prioritizing low quiescent current.
• Industrial IoT sensors and controllers operating in harsh environmental conditions.

Procurement Notes

Verify the specific suffix codes on the ordering information to confirm the exact output voltage combination and package type, as variations exist within the S-1701 family. Ensure compliance with RoHS directives and check for automotive qualification status if required for safety-critical designs. Confirm lead times and minimum order quantities directly with authorized distributors or the manufacturer, as these parameters are subject to change based on production schedules and supply chain conditions.

Selection Notes

Select this component when a design requires two distinct regulated outputs from a single IC to save board space and reduce component count. It is suitable for applications where input voltage varies between 2 V and 6.5 V and where low static current is critical for efficiency. Consider the SOT-23-5 package constraints regarding thermal dissipation and pin pitch during PCB layout. Compare against single-output LDOs if only one rail is needed, but utilize this dual-output solution for cost and area optimization in multi-rail architectures.

Part Context

The S-1701 series represents ABLIC's lineup of high-reliability linear regulators tailored for automotive and general-purpose electronic equipment. These devices combine voltage regulation with voltage detection capabilities, offering a compact solution for power management. The S-1701A5041-M5T1G specifically addresses the need for precise 4.1 V and 5.0 V generation in space-constrained environments, leveraging CMOS technology for low power consumption and robust performance across wide temperature ranges.

Replacement Considerations

Direct replacements may include other S-1701 variants with different output voltage combinations, such as S-1701E5042-U5T1G or S-1701D5043-M5T1G, provided the voltage levels match the application requirements. Verify pin compatibility and thermal characteristics before substitution. Cross-reference with similar dual-output LDOs from other manufacturers only if electrical specifications and package dimensions are identical.
