S-1701U3328-M5T1G

Overview

The S-1701U3328-M5T1G is a dual-output low-dropout (LDO) voltage regulator manufactured by ABLIC Inc., featuring integrated voltage detection capabilities. It provides fixed output voltages of 2.8 V and 3.3 V with a maximum output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical quiescent current of 85 µA. Key electrical specifications include a line regulation of 0.2 %/V, load regulation of 40 mV, and a dropout voltage of 140 mV at rated conditions. Voltage accuracy is specified at 1 %. The component supports surface-mount installation in an SOT-23-5 package and functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates dual LDO regulators with combined voltage detection functionality for system monitoring
• Delivers high output current capability up to 400 mA while maintaining ultra-low standby power consumption
• Ensures stable performance through precise voltage regulation and low dropout characteristics

Applications

• Portable electronic devices requiring efficient multi-rail power management
• Battery-powered systems needing extended operational life through low quiescent current
• Embedded circuits requiring simultaneous voltage regulation and supply monitoring

Procurement Notes

Verify the specific output voltage configuration matches the target application requirements before integration. Confirm that the thermal dissipation capabilities of the SOT-23-5 package are sufficient for the expected load conditions. Ensure compatibility with the manufacturing process regarding the surface-mount mounting style. Cross-reference the latest datasheet for any updates on environmental compliance or pinout definitions to guarantee correct PCB layout implementation.

Selection Notes

Select this component when a design requires two distinct regulated voltage rails alongside voltage supervision in a compact footprint. The choice is appropriate for applications prioritizing low power consumption during idle states without sacrificing significant load current capacity. Consider the input voltage range constraints relative to the available power source. Evaluate the thermal performance under maximum load to ensure the junction temperature remains within safe operating limits for the intended environment.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed to consolidate power management and monitoring functions into a single small package. This specific model variant offers fixed outputs tailored for common logic levels, providing a streamlined solution for designers aiming to reduce component count and board space in portable and battery-operated electronics.

Replacement Considerations

Direct substitutes within the same series include S-1701W3328-M5T1G and S-1701R3328-M5T1G, which share identical electrical characteristics but differ in packaging options such as UFBGA or WLBGA. Verify pin compatibility and thermal properties when considering alternative packages from the same manufacturer.
