S-1701N3315-U5T1G

Overview

The S-1701N3315-U5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, housed in an SOT-23-5 surface-mount package. It provides fixed output voltages of 1.5 V and 3.3 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 dropout voltage of 140 mV at rated load. It features high voltage regulation accuracy of ±1% and supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Dual independent fixed output channels providing 1.5 V and 3.3 V simultaneously
• High precision voltage regulation with ±1% output accuracy
• Low quiescent current consumption for efficient power management
• Integrated overcurrent protection and thermal shutdown circuits

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems needing efficient linear regulation
• Embedded control circuits in consumer electronics
• IoT modules requiring compact dual-voltage power solutions

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-23-5 package and reel packaging configuration. Confirm that the N3315 designation matches the required 1.5 V and 3.3 V output combination. Ensure compatibility with standard SMD/SMT assembly processes. Check for RoHS compliance documentation if required by your manufacturing standards. Validate lead times as they may vary based on production schedules.

Selection Notes

Select this component when a single IC solution is needed to generate two distinct fixed voltages from a single input source. It is suitable for designs where space constraints favor the SOT-23-5 package over larger alternatives. Consider its 400 mA current capability against the peak load requirements of both output rails. Evaluate the 140 mV dropout voltage against the minimum input voltage available in your system to ensure stable regulation under all operating conditions.

Part Context

This part belongs to the ABLIC S-1701 series of combo voltage detector/regulators. The series is characterized by low current consumption and high accuracy, designed for portable applications. The S-1701 family offers various output voltage combinations and packages, including SOT-89-5 and SOT-23-5, allowing designers to choose based on power and size requirements.

Replacement Considerations

Direct substitutes within the same series include other S-1701 variants with different output voltage pairs or package options, such as S-1701R1815-U5T1G or S-1701E3026-U5T1G, provided the electrical specifications meet the design requirements. Verify pinout compatibility before substitution.
