S-1701F3026-U5T1G

Overview

The S-1701F3026-U5T1G is a low dropout voltage regulator from the ABLIC S-1701 series, housed in an SOT-89-5 package. It provides dual fixed output voltages of 2.6 V and 3.0 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 140 mV. It operates within a temperature range of -40°C to +85°C and includes built-in protection circuits for overcurrent and thermal shutdown.

Feature Summary

• Dual-channel architecture providing independent 2.6 V and 3.0 V outputs
• Ultra-low quiescent current consumption for extended battery life
• Integrated reverse current protection function
• Built-in overcurrent and thermal shutdown protection circuits

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems with strict power consumption constraints
• Embedded control units needing combined regulation and detection capabilities

Procurement Notes

Verify the specific suffix U5T1G against the manufacturer's latest datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure that the required output currents do not exceed the 400 mA limit per channel under all operating conditions. Confirm RoHS compliance status directly with the supplier documentation prior to finalizing procurement orders.

Selection Notes

Select this component when dual voltage outputs are required from a single package to save board space. The S-1701 series is suitable for applications prioritizing low standby current over high efficiency at heavy loads. Compare the 140 mV dropout specification against system requirements to ensure adequate headroom between input and output voltages during operation.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. These devices integrate LDO functionality with voltage monitoring features in a compact surface-mount package. The series is designed for portable equipment where size and power efficiency are critical design parameters.

Replacement Considerations

Check for direct substitutes within the S-1701 family sharing the same SOT-89-5 footprint and electrical characteristics. Verify that alternative parts offer compatible output voltages and current ratings before substitution.
