S-1701W3326-U5T1G

Overview

The S-1701W3326-U5T1G is a dual-output low dropout (LDO) voltage regulator from ABLIC's S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 2.6 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 up to 6.0 V. Key electrical specifications include a line regulation of 0.2 %/V, load regulation of 40 mV, and a power dissipation rating of 1 W. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates two independent LDO regulators and a voltage detector function within a single compact package.
• Maintains stable output voltage under varying load conditions with low dropout characteristics.
• Optimized for battery-powered applications through ultra-low quiescent current consumption.

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-operated systems needing extended operational life
• Embedded circuits utilizing combined regulation and voltage monitoring

Procurement Notes

Verify the specific part number suffix against official ABLIC documentation to confirm pinout compatibility and thermal ratings. Ensure that the required output voltages match the fixed internal settings, as adjustable variants are not available in this configuration. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a design requires two distinct fixed voltage outputs alongside voltage detection functionality in a space-constrained environment. Evaluate the total power dissipation capabilities relative to the ambient temperature and PCB copper area. Consider the 400 mA output limit and ensure it meets the peak current demands of both downstream loads simultaneously without exceeding thermal constraints.

Part Context

This model belongs to the S-1701 series, which combines linear regulation with voltage detection capabilities. It is designed for general-purpose power management in consumer electronics and industrial equipment. The SOT-89-5 package offers a balance between thermal performance and board space efficiency compared to smaller packages like SOT-23-5.

Replacement Considerations

Direct substitutes within the same series include S-1701E3026-U5T1G and S-1701Y3342-U5T1G, provided their specific output voltage combinations align with system requirements. Verify pin-to-pin compatibility and thermal characteristics before swapping components in existing designs.
