S-1701N5015-U5T1G

Overview

The S-1701N5015-U5T1G is a dual-output low dropout (LDO) voltage regulator manufactured by ABLIC Inc. It features two fixed positive output voltages of 1.5 V and 5.0 V, with a maximum output current of 400 mA per channel. The device operates within an input voltage range supporting these outputs and maintains a quiescent current of 85 µA. It utilizes an SOT-89-5 surface-mount package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual independent LDO regulators in a single compact package
• Provides fixed output voltage options for simultaneous multi-rail power requirements
• Includes built-in voltage detection functionality alongside regulation

Applications

• Portable electronic devices requiring multiple supply rails
• Embedded systems with microcontrollers and peripheral logic
• Battery-powered equipment needing efficient power management

Procurement Notes

Verify the specific output voltage combination matches the design requirement, as the S-1701 series offers various fixed voltage pairs. Confirm the SOT-89-5 package orientation and pinout compatibility with the PCB footprint. Ensure the thermal dissipation capabilities of the application board support the expected load currents and ambient temperatures.

Selection Notes

Select this component when dual regulated supplies are needed from a single source without external switching complexity. Compare the dropout voltage specifications against the minimum input voltage available in the system. Evaluate the total current consumption including the 85 µA quiescent draw to ensure it meets battery life or efficiency targets for the target application.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs from ABLIC. The series is characterized by low current consumption and high accuracy, designed for space-constrained applications. The N5015 suffix indicates the specific 1.5 V and 5.0 V output configuration within the broader product family.

Replacement Considerations

Direct substitutes within the same series include other S-1701 variants with different fixed voltage combinations such as S-1701R1815-U5T1G or S-1701E3026-U5T1G, provided the voltage requirements differ. Cross-referencing datasheets is essential to verify identical pinouts and electrical characteristics before substitution.
