S-1701T3315-U5T1G

Overview

The S-1701T3315-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 features a typical quiescent current of 85 µA and supports an input voltage range from 2 V to 6.5 V. Key electrical specifications include a line regulation of 0.2 %/V, load regulation of 40 mV, and a power dissipation rating of 420 mW. It operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates two independent fixed-voltage LDO regulators with integrated voltage detection functionality in a single compact package.
• Maintains stable performance with ultra-low quiescent current consumption suitable for battery-powered applications.
• Provides high output drive capability up to 400 mA while ensuring precise voltage regulation accuracy.

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-operated systems prioritizing low standby power consumption
• Embedded circuits needing combined voltage regulation and monitoring

Procurement Notes

Verify the specific suffix U5T1G against official ABLIC documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure the ordering quantity aligns with manufacturer packaging constraints. Cross-reference the datasheet revision date to validate thermal characteristics and absolute maximum ratings before final integration.

Selection Notes

Select this component when dual fixed outputs of 1.5 V and 3.3 V are required in a space-constrained design. The SOT-23-5 package offers a smaller footprint compared to SOT-89 variants. Consider the 420 mW power dissipation limit relative to ambient temperature and PCB copper area for adequate thermal management during operation.

Part Context

This part belongs to the S-1701 family of combo voltage detectors and regulators. Unlike single-output models such as the S-13A1 series, this variant integrates two distinct regulated outputs. It shares the series' characteristic low quiescent current but differs in package type and output configuration from larger SOT-89-5 counterparts like the S-1701R1815-U5T1G.

Replacement Considerations

Direct substitutes include other S-1701 series parts with identical output voltages and packages, such as S-1701N3315-M5T1G or S-1701T3315-M5T1G, provided the pinout suffix matches exactly. Verify that alternative packages maintain compatible thermal resistance values.
