S-1701E3026-M5T1G

Overview

The S-1701E3026-M5T1G is a dual-output low dropout (LDO) voltage regulator and voltage detector integrated circuit manufactured by ABLIC. It features two fixed positive output voltages of 2.6 V and 3.0 V, with a maximum output current capability 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 specified load conditions. It incorporates a low quiescent current of 85 µA, enhancing efficiency in battery-powered applications. The component is housed in a compact SOT-89-5 surface-mount package and is rated for operation across a temperature range of -40 °C to +85 °C.

Procurement Notes

Verify the exact suffix 'M5T1G' matches the required packaging and tape-and-reel specifications. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations. Ensure the ordering part number aligns precisely with the desired output voltage combination of 2.6 V and 3.0 V. Cross-reference the datasheet revision date to confirm technical parameters have not changed. Validate that the SOT-89-5 package dimensions match your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when dual independent regulated outputs are needed from a single IC to save board space. Consider the 400 mA output current rating to ensure it meets the peak load demands of both rails. Evaluate the 140 mV dropout voltage against the minimum expected input voltage to maintain regulation. Assess the 85 µA quiescent current impact on overall system battery life. Verify that the operating temperature range of -40 °C to +85 °C covers the intended environmental conditions. Compare pinout compatibility if replacing existing designs using similar packages.
