S-1701E3327-M5T1G

Overview

The S-1701E3327-M5T1G is a low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It integrates a dual-output linear regulator with a voltage detector circuit within a single package. The device provides two fixed output voltages of 2.7 V and 3.3 V, supporting a maximum output current of 400 mA. It features a typical quiescent current of 85 µA and operates within an input voltage range of 2 V to 6.5 V. The component utilizes an SOT-23-5 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a dual-output LDO regulator and a voltage detector in a compact footprint
• Provides fixed 2.7 V and 3.3 V outputs with high current capability
• Features ultra-low quiescent current for extended battery life
• Includes built-in protection mechanisms such as thermal shutdown

Applications

• Battery-powered portable electronic devices requiring stable dual rails
• Microcontroller unit (MCU) power supply systems
• Voltage monitoring circuits in embedded systems
• Low-power consumer electronics and IoT modules

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and electrical tolerances. Ensure the ordering information matches the required output voltage combination and package type. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a design requires both regulated power and voltage supervision from a single source. The dual-output configuration simplifies board layout compared to using separate regulator and detector ICs. Consider the 400 mA current rating to ensure it meets the peak load requirements of the connected logic circuits. Verify that the input voltage range aligns with the available power source.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed to reduce component count and board space in power management applications. Similar parts in the family may offer different output voltage combinations or package options, but share the same core integration architecture and low-power characteristics.

Replacement Considerations

Direct replacements must match the SOT-23-5 package and dual-output specification. Verify that substitute parts maintain equivalent quiescent current and dropout voltage characteristics. Check for compatible thermal performance and operating temperature ranges before integrating alternative components.
