S-1701F5043-M5T1G

Overview

The S-1701F5043-M5T1G is a low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, featuring an integrated voltage detector. It provides two fixed positive output voltages: 4.3 V and 5 V. The device supports a maximum output current of 400 mA with a typical quiescent current of 85 µA. It operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 140 mV. The component functions reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Combines a dual-output LDO regulator with a voltage detection function in a single package
• Delivers high output current capability of up to 400 mA for demanding load applications
• Maintains ultra-low standby power consumption through minimal quiescent current draw
• Ensures stable regulation with low dropout voltage characteristics under varying load conditions

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Embedded systems needing simultaneous multiple voltage rails for logic and peripherals
• Microcontroller units requiring precise voltage supervision and reset generation
• Consumer electronics utilizing lithium-ion or lithium-polymer battery sources

Procurement Notes

Verify the specific output voltage combination of 4.3 V and 5 V matches your circuit requirements before ordering. Confirm the SOT-23-5 package footprint aligns with your PCB layout. Ensure the operating temperature range of -40°C to +85°C suits your environmental conditions. Check for any recent Product Change Notifications regarding manufacturing updates. Validate that the 400 mA output current rating meets your peak load demands.

Selection Notes

Select this component when dual fixed outputs are required without external resistors. Consider the 85 µA quiescent current for battery life optimization. Evaluate the 140 mV dropout voltage against your minimum input voltage constraints. Compare the SOT-23-5 size against available board space. Assess the need for integrated voltage detection versus separate supervisor ICs.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. The series is designed for low-power applications integrating regulation and monitoring. Other variants in the family offer different output voltage combinations while sharing similar electrical characteristics and packaging options. The series targets cost-sensitive and space-constrained designs in consumer and industrial markets.

Replacement Considerations

Direct substitutes may include other S-1701 series parts with identical 4.3 V and 5 V outputs but different suffixes indicating minor revisions. Verify pin compatibility and thermal performance when cross-referencing with competitors' dual-output LDOs. Ensure equivalent quiescent current and dropout specifications for functional parity.
