S-1701B3327-U5T1G

Overview

The S-1701B3327-U5T1G is a high ripple-rejection low dropout CMOS voltage regulator with an integrated reset function, manufactured by ABLIC Inc. It operates within an input voltage range of 2V to 6.5V and provides a fixed output voltage of 3.3V. The device features a typical quiescent current of 85µA and supports a maximum output current of 400mA. It is housed in a compact SOT-89-5 package, designed for efficient power management in space-constrained applications.

Feature Summary

• Integrates a voltage detector with reset functionality for system protection
• High ripple rejection ratio for stable operation under noisy conditions
• Low quiescent current consumption for extended battery life
• Compact SOT-89-5 package suitable for dense PCB layouts

Applications

• Battery-powered portable devices
• Voltage converter circuits
• Embedded systems requiring stable supply rails
• Microcontroller power management units

Procurement Notes

Verify the specific suffix B3327 confirms the 3.3V output variant. Confirm the U5T1G suffix matches the required SOT-89-5 tape and reel packaging configuration. Check for 'Not For New Designs' status if available in official distributor catalogs to assess long-term availability risks before finalizing procurement plans.

Selection Notes

Select this component when a fixed 3.3V output is required alongside hardware reset generation. Ensure the input voltage remains between 2V and 6.5V. Verify that the 400mA load capability meets the target circuit demands. Consider the thermal performance of the SOT-89-5 package under expected operating conditions.

Part Context

This part belongs to the S-1701 series of low dropout regulators from ABLIC. The series is characterized by high ripple rejection and integrated voltage detectors. Variants differ primarily by output voltage and package type, with the B3327 designation specifically indicating the 3.3V output version within this family.

Replacement Considerations

Cross-reference with other S-1701 variants such as S-1701C3327 or S-1701D3327 for pin-compatible alternatives with different output tolerances or temperature ranges. Verify electrical specifications match exactly before substitution.
