S-1701C3024-U5T1G

Overview

The S-1701C3024-U5T1G is a CMOS-based low-dropout voltage regulator manufactured by ABLIC Inc. It integrates a fixed 3V output with a high-accuracy voltage detector, providing a combined reset function. The device operates within an input voltage range up to 6.5V and delivers a maximum output current of 400mA. Key electrical parameters include a typical quiescent current of 85µA and a maximum dropout voltage of 210mV at 100mA load. It features line regulation of 0.2%/V and load regulation of 40mV. The component is housed in a surface-mount SOT-89-5 package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a fixed 3V LDO regulator with a high-accuracy voltage detector for system reset functionality
• Provides low power consumption with a typical quiescent current of 85µA
• Delivers high output current capability up to 400mA with low dropout characteristics
• Utilizes CMOS technology for compact surface-mount integration

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Embedded systems needing integrated voltage supervision and reset signals
• Microcontroller unit (MCU) power supply circuits with voltage monitoring requirements
• Communication modules requiring stable 3V logic levels and brown-out protection

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 package and reel packaging configuration as listed in official distributor catalogs. Confirm that the C-series designation aligns with the intended thermal or performance specifications for your application environment. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-chip solution combining voltage regulation and detection is required to save board space. The 3V fixed output suits 3.3V logic systems operating at reduced voltages. Consider the 400mA output current limit against peak load demands. The SOT-89-5 package offers a balance between thermal dissipation and footprint size compared to smaller alternatives like SOT-23-5.

Part Context

This part belongs to the S-1701 series of special-purpose voltage regulators developed by ABLIC Inc. based on CMOS technology. The series is characterized by integrating high-accuracy voltage detectors with regulators to provide reset functions. Variants within the series differ by output voltage, package type, and specific detector thresholds, catering to diverse embedded power management needs.

Replacement Considerations

Direct substitutes include other S-1701 series variants such as S-1701B3024-U5T1G or S-1701E3024-M5T1G, which share similar functional architectures but may differ in package style or specific electrical tolerances. Verify pinout compatibility and thermal performance before substitution.
