S-1701B3328-M5T1G

Overview

The S-1701B3328-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC manufactured by ABLIC. It features two fixed output voltages of 3.3 V and 2.8 V, with a maximum output current of 400 mA. The device operates within an input voltage range typical for battery-powered applications and maintains a low quiescent current of 85 µA. It is housed in a compact SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates dual-output LDO regulation with a built-in voltage detector function
• Optimized for low power consumption with ultra-low quiescent current operation
• Provides stable regulated outputs suitable for sensitive digital logic and memory circuits

Applications

• Battery-powered portable electronic devices
• Voltage monitoring in microcontroller systems
• Power management for mobile communication modules

Procurement Notes

Verify the specific suffix M5T1G confirms the SOT-23-5 package and reel packaging format. Ensure compatibility with the required 3.3 V and 2.8 V output levels. Confirm RoHS compliance status through official manufacturer documentation before integration into production designs.

Selection Notes

Select this component when dual voltage rails are needed from a single regulator unit. The integrated voltage detector simplifies system design by eliminating external monitoring components. Consider the 400 mA output capability against load requirements and the thermal performance within the specified operating temperature range.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed for battery-operated equipment requiring efficient power management. Similar parts in the family vary by output voltage combinations and package types, such as SOT-89-5 variants.

Replacement Considerations

Direct substitutes include other S-1701 series parts with matching output voltages and packages, such as S-1701A3328-M5T1G or S-1701W1626-M5T1G, provided pinouts and electrical characteristics align with the original design requirements.
