S-1701D5040-M5T1G

Overview

The S-1701D5040-M5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, housed in an SOT-23-5 surface-mount package. It provides fixed output voltages of 4.3 V and 5 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 210 mV at 100 mA. It operates within an input voltage range of 2 V to 6.5 V and maintains a voltage regulation accuracy of 1%. The unit supports a power dissipation of 420 mW and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture delivering independent 4.3 V and 5 V fixed outputs simultaneously
• Ultra-low standby current consumption of 85 µA for extended battery life
• High current capability of 400 mA per output with stable performance under load
• Integrated voltage detection functionality combined with linear regulation

Applications

• Portable electronic devices requiring efficient multi-voltage rail generation
• Battery-powered systems prioritizing low quiescent current operation
• Embedded circuits needing precise voltage monitoring and regulation
• Compact consumer electronics utilizing space-constrained SOT-23-5 packaging

Procurement Notes

Verify the specific suffix M5T1G against official ABLIC documentation to confirm the exact reel quantity and tape-and-reel specifications. Ensure the ordering part number matches the required output voltage combination of 4.3 V and 5 V. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single IC must provide two distinct regulated rails (4.3 V and 5 V) with high efficiency. The SOT-23-5 package suits applications with strict board space limitations. Consider the 420 mW power dissipation limit relative to ambient temperature and thermal design constraints. Verify that the input voltage range of 2 V to 6.5 V aligns with the system's power source characteristics.

Part Context

This model belongs to the S-1701 series of combo voltage detector/regulator LDOs. It shares the series' core architecture but differs in output voltage configuration and package type from other variants like the S-1701E or S-1701Q series. The D-series designation typically indicates specific pinout or thermal characteristics within the broader product family.

Replacement Considerations

Cross-reference with S-1701F5043-M5T1G if a 4.3 V/5 V output pair is needed in the same SOT-23-5 package. Verify pin compatibility and thermal performance before substitution.
