S-1701E5041-M5T1G

Overview

The S-1701E5041-M5T1G is a low-dropout regulator and voltage detector combo IC from ABLIC. It features two fixed positive outputs: 4.1 V and 5 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 dropout voltage of 140 mV at 100 mA. It integrates a built-in voltage detector with a reset output threshold of 4.63 V ±2%. Quiescent current is typically 85 µA. The unit supports surface-mount installation in a compact SOT-23-5 package and functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Combines dual-output LDO regulation with integrated voltage detection for space-constrained designs
• Provides stable power delivery with low quiescent current consumption for battery efficiency
• Includes hardware reset functionality triggered by specific voltage thresholds

Applications

• Power management for portable electronic devices requiring multiple voltage rails
• Voltage supervision circuits in microcontroller-based systems
• Battery-powered equipment needing efficient step-down regulation

Procurement Notes

Verify the exact part number against official ABLIC documentation to confirm pinout compatibility and electrical specifications. Ensure that the selected variant matches the required output voltages and package type for your specific circuit design. Cross-reference datasheets for thermal performance and load regulation characteristics before finalizing procurement decisions.

Selection Notes

Select this component when designing systems that require simultaneous regulated power supply and voltage monitoring in a minimal footprint. Consider the 400 mA output capability and low dropout characteristics for applications with varying load conditions. Evaluate the thermal dissipation requirements based on the SOT-23-5 package limitations and expected ambient temperatures.

Part Context

This device belongs to the S-1701 series of combo voltage detectors and regulators manufactured by ABLIC Inc. The series is designed to integrate power management and system supervision functions into a single small package, reducing component count and board space in modern electronic applications.

Replacement Considerations

Direct substitutes include other ABLIC S-1701 series variants with compatible output voltages and packages, such as S-1701D5043-M5T1G or S-1701F5043-M5T1G, provided the electrical parameters align with the design requirements.
