S-1701C5042-M5T1G

Overview

The S-1701C5042-M5T1G is a low dropout voltage regulator manufactured by ABLIC, featuring an integrated voltage detector within the SOT-23-5 surface-mount package. It provides two fixed output voltages of 4.2 V and 5 V with a maximum continuous output current of 400 mA. The device operates with a quiescent current of 85 µA and supports an input voltage range from 2 V to 6.5 V. It maintains a typical dropout voltage of 140 mV and ensures voltage regulation accuracy of 1%. The component functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrates a linear regulator and voltage detector in a single compact package
• Provides dual fixed output voltages for simultaneous power supply needs
• Maintains low quiescent current consumption for efficient power management
• Ensures stable operation with high voltage regulation accuracy

Procurement Notes

Verify the specific suffix codes against the official ABLIC datasheet to confirm pinout compatibility and thermal characteristics. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm RoHS compliance status through the latest product change notifications before finalizing procurement contracts.

Selection Notes

Select this component when dual fixed outputs are required alongside voltage monitoring capabilities. The SOT-23-5 package suits space-constrained designs. Verify that the 400 mA load current does not exceed thermal limits at the maximum operating temperature. Compare dropout performance against system headroom requirements to ensure stable regulation under varying load conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed for applications requiring both power regulation and system supervision. ABLIC utilizes this platform to provide cost-effective solutions for embedded systems. The S-1701C5042 variant specifically targets designs needing 4.2 V and 5 V rails simultaneously.

Replacement Considerations

Direct substitutes include other S-1701 series variants with compatible output voltages such as S-1701D5043-M5T1G or S-1701F5043-M5T1G. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Consult ABLIC documentation for cross-reference recommendations.
