S-1701A5043-U5T1G

Overview

The ABLIC S-1701A5043-U5T1G is a dual-output low-dropout (LDO) voltage regulator featuring an integrated voltage detector. It provides fixed output voltages of 4.3 V and 5.0 V with a maximum continuous output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V, ensuring stable regulation under varying supply conditions. Key electrical specifications include a typical quiescent current of 85 µA and a dropout voltage of approximately 140 mV at rated load. The component supports surface-mount installation in an SOT-23-5 package, designed for efficient power management in space-constrained applications.

Feature Summary

• Dual-channel fixed output configuration providing independent 4.3 V and 5.0 V rails from a single input source
• Integrated voltage detection functionality combined with linear regulation for comprehensive power monitoring
• Ultra-low standby current consumption optimized for battery-powered and energy-efficient system designs

Applications

• Portable electronic devices requiring simultaneous multi-voltage rail generation
• Embedded systems utilizing microcontrollers needing dedicated logic and peripheral power supplies
• Battery-operated equipment where extended operational life depends on minimal quiescent drain

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure that the required output tolerances align with the target circuit design before finalizing procurement orders. Cross-reference the manufacturing date codes to guarantee compliance with current environmental standards and RoHS directives applicable to your region.

Selection Notes

Select this component when a compact solution is needed to generate two distinct regulated voltages from a single unregulated source. The SOT-23-5 footprint offers a balance between current handling capability and board space efficiency. Consider the input voltage headroom requirements relative to the dropout characteristics to maintain regulation stability across the entire operating temperature range specified by the manufacturer.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators manufactured by ABLIC Inc. The series is characterized by its integration of LDO regulation and voltage monitoring functions into a single small-outline package. This specific model variant utilizes the U5T1G designation, indicating a particular tape-and-reel packaging format suitable for automated surface-mount assembly processes in high-volume production environments.

Replacement Considerations

Direct substitutes within the same series include S-1701D5043-M5T1G and S-1701F5043-M5T1G, which share identical electrical outputs but differ in package type. Verify pin-to-pin compatibility and thermal dissipation requirements when transitioning between SOT-23-5 and SOT-89-5 packages to ensure proper heat management in the final application.
