S-1701E5042-M5T1G

Overview

The S-1701E5042-M5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, manufactured by ABLIC Inc. It provides fixed output voltages of 4.2 V and 5 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and operates within an input voltage range up to 6.5 V. It utilizes an SOT-23-5 surface-mount package and maintains a low dropout voltage of 140 mV at rated load. The unit supports a wide operating temperature range from -40°C to +85°C and includes integrated voltage detection functionality.

Feature Summary

• Dual independent fixed voltage outputs for simultaneous power rail generation
• Ultra-low quiescent current consumption for extended battery life in portable devices
• Integrated voltage detector circuit for system monitoring and reset control
• Compact SOT-23-5 package design optimized for space-constrained applications

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems needing efficient power management
• Embedded controllers requiring integrated voltage supervision
• Consumer electronics with strict size and power constraints

Procurement Notes

Verify the specific suffix M5T1G against official ABLIC documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the SOT-23-5 configuration. Cross-reference the part number with authorized distributors to confirm current availability and lead times. Validate that the 4.2 V and 5 V output combination meets your system's electrical requirements before finalizing procurement.

Selection Notes

Select this component when dual fixed outputs are required without external resistors. The 400 mA output current capability suits moderate load applications. Consider the 85 µA quiescent current for battery-operated designs where standby power is critical. Verify that the input voltage remains within the specified limits to ensure proper regulation and avoid excessive power dissipation in the SOT-23-5 package.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed for automotive and industrial applications requiring high reliability. ABLIC integrates voltage detection functions alongside linear regulation to reduce component count. The S-1701 family offers various output voltage combinations and packages to suit different design needs.

Replacement Considerations

Check ABLIC datasheets for other S-1701 variants with similar output voltages. Verify pinout compatibility if substituting with different package options like SOT-89-5. Ensure thermal performance matches your application requirements when considering alternatives.
