S-1701F2522-M5T1G

Overview

The S-1701F2522-M5T1G is a low-dropout regulator (LDO) voltage detector combo IC from ABLIC, housed in an SOT-23-5 package. It provides a fixed 2.2V output with a maximum current of 400mA and features a typical quiescent current of 85µA. The device integrates a voltage detector function that monitors the input voltage against a threshold, providing a reset signal when the supply drops below the specified level. Designed for automotive applications, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Combines LDO regulation with voltage detection functionality
• Low quiescent current consumption for power efficiency
• Automotive-grade reliability and wide operating temperature range

Applications

• Automotive electronic control units
• Battery-powered systems requiring voltage monitoring
• Microprocessor reset circuits

Procurement Notes

Verify the specific output voltage and detector threshold parameters against the official datasheet before procurement, as suffixes define these electrical characteristics. Confirm RoHS compliance status and ensure the SOT-23-5 package footprint matches your PCB design requirements. Check for any recent product change notifications that may affect pinout or performance specifications.

Selection Notes

Select this component when a combined LDO and voltage detector solution is required to save board space. Ensure the input voltage range supports the desired output and that the load current does not exceed 400mA. Consider the dropout voltage characteristics relative to your minimum input supply voltage to maintain regulation under all operating conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed for automotive applications, offering high reliability and low power consumption. Similar parts in the series vary by output voltage and detector threshold settings, allowing for flexible configuration in various power management architectures.

Replacement Considerations

Direct replacements must match the SOT-23-5 package and provide equivalent 2.2V output and 400mA current capability. Verify that alternative components offer similar quiescent current and voltage detector thresholds to ensure system compatibility without redesign.
