S-1701A5041-U5T1G

Overview

The S-1701A5041-U5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 4.1 V and 5.0 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 210 mV at 100 mA load. It operates within an input voltage range supporting these outputs and maintains a working temperature range from -40°C to +85°C. Voltage regulation accuracy is specified at 1%, with line regulation of 0.2%/V and load regulation of 40 mV.

Feature Summary

• Dual independent fixed output channels for simultaneous supply generation
• Ultra-low quiescent current consumption for battery efficiency
• Low dropout voltage characteristics for high efficiency under varying loads
• Integrated voltage detection functionality combined with regulation

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems needing efficient power management
• Embedded circuits requiring precise voltage references

Procurement Notes

Verify the specific output voltage combination (4.1 V and 5.0 V) matches your circuit design requirements before ordering. Confirm the SOT-89-5 package footprint compatibility with your PCB layout. Ensure the thermal dissipation capabilities of the SOT-89-5 package are sufficient for your expected load conditions and ambient temperature. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when dual fixed outputs are needed without external resistors. The S-1701 series offers high accuracy and low noise suitable for sensitive analog sections. Compare dropout voltage specifications against your minimum input voltage constraints. Consider the 400 mA current limit for peak load demands. Evaluate thermal performance based on power dissipation calculations for the specific application environment.
