S-1701C1815-U5T1G

Overview

The S-1701C1815-U5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, manufactured by ABLIC Inc. It integrates two fixed output channels providing 1.5 V and 1.8 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and operates within an input voltage range of 2 V to 6.5 V. It utilizes an SOT-89-5 surface-mount package and supports a junction temperature range from -40 °C to +85 °C. Key electrical characteristics include a line regulation of 0.2 %/V, load regulation of 40 mV, and a power dissipation rating of 1 W.

Feature Summary

• Integrates dual independent fixed voltage outputs for simultaneous supply requirements
• Combines low quiescent current operation with high output drive capability
• Includes built-in voltage detection functionality alongside regulation

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Embedded systems needing combined regulation and voltage monitoring
• Battery-powered equipment prioritizing low standby power consumption

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm pinout compatibility and thermal specifications. Ensure the ordering quantity aligns with standard factory packaging multiples. Confirm RoHS compliance status through the latest product change notifications before final procurement decisions.

Selection Notes

Select this component when dual fixed voltages are required in a compact footprint. Compare dropout voltage specifications against your minimum input voltage constraints. Evaluate thermal performance based on expected power dissipation within the SOT-89-5 package limits.

Part Context
