S-1701X3228-U5T1G

Special Purpose Regulators Overview

The S-1701X3228-U5T1G is a low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, manufactured using CMOS technology. It integrates a high-accuracy voltage detector and a reset function within a single package. The device features a fixed output voltage of 2.8 V with an accuracy of ±1%. It supports a maximum output current of 400 mA and operates with an input voltage range of 2 V to 6.5 V. Key electrical parameters include a typical quiescent current of 85 µA, a dropout voltage of 540 mV at full load, line regulation of 0.2 %/V, and load regulation of 40 mV. The unit is housed in an SOT-23-5 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Special Purpose Regulators Feature Summary

Special Purpose Regulators Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure the ordering quantity aligns with manufacturer reel standards. Confirm RoHS compliance status through the latest product change notifications or datasheet revisions prior to final procurement decisions.

Special Purpose Regulators Selection Notes

Select this component when a combined LDO and voltage detection solution is required in a minimal footprint. The SOT-23-5 package suits space-constrained designs. Consider the 400 mA output capability and 2.8 V fixed output level against load requirements. Verify that the 2 V minimum input voltage meets the lowest expected supply rail conditions during operation.

Special Purpose Regulators Part Context

This part belongs to the S-1701 series of CMOS-based voltage regulators. The series is characterized by integrating voltage detectors and reset functions alongside standard LDO capabilities. This integration reduces component count in applications requiring both power regulation and system supervision, distinguishing it from standalone regulators or separate detector ICs.

Special Purpose Regulators Replacement Considerations

Direct substitutes within the same series include parts with identical output voltages and package types, such as the S-1701Z3228-U5T1G. Cross-referencing pin configurations and thermal performance is essential when considering alternative manufacturers or different series variants.
