S-1701E5041-U5T1G

Overview

The S-1701E5041-U5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, designed for applications requiring combined voltage regulation and detection. It features two fixed positive output voltages of 4.1 V and 5 V, with a maximum continuous 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. It utilizes a SOT-89-5 surface-mount package and supports operation across a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates dual LDO regulators with built-in voltage detector functionality in a single compact package
• Provides high output current capability of 400 mA per channel for powering multiple loads
• Maintains low power consumption with a typical quiescent current of 85 µA during operation

Applications

• Portable electronic devices requiring efficient multi-voltage rail generation
• Embedded systems needing integrated voltage monitoring and regulation
• Battery-powered equipment prioritizing extended operational life through low standby current

Procurement Notes

Verify the specific output voltage combination against the official datasheet, as suffixes define the exact voltage pairs. Confirm the package type matches the design footprint requirements. Ensure the operating temperature range aligns with the environmental conditions of the target application. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and availability.

Selection Notes

Select this component when a dual-output solution with voltage detection is required to save board space. Consider the 400 mA output current limit to ensure it meets the peak load demands of the connected circuits. Evaluate the dropout voltage characteristics relative to the minimum input voltage available in the system to maintain stable regulation under all operating conditions.

Part Context

This regulator belongs to the S-1701 series by ABLIC Inc., which specializes in low-power linear regulators. The series is characterized by its integration of voltage detection functions alongside standard regulation, making it suitable for complex power management tasks in consumer electronics and industrial control systems where size and efficiency are critical constraints.

Replacement Considerations

Check for other variants within the S-1701 family that offer different fixed voltage combinations or alternative packages such as SOT-23-5 if pinout compatibility allows. Verify functional equivalence regarding output current ratings and quiescent current specifications before substituting.
