S-1701P3338-U5T1U

Overview

The S-1701P3338-U5T1U is a CMOS voltage regulator from the S-1701 series, manufactured by ABLIC Inc. It integrates a high-accuracy voltage detector and features a reset function. The device provides a fixed output voltage of 3.3 V with a single output channel. It operates within an input voltage range of 1.5 V to 5.5 V and supports an output current of 1 A. The unit is housed in an SOT-89-5 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-accuracy voltage detector for precise monitoring
• Includes a built-in reset function for system protection
• Utilizes CMOS technology for low dropout performance

Applications

• Battery-powered devices requiring stable voltage conversion
• Systems needing integrated voltage detection and reset capabilities
• Portable electronics utilizing surface-mount power management

Procurement Notes

Verify the specific suffix U5T1U against official ABLIC documentation to confirm pinout and functional configuration. Ensure compatibility with existing PCB footprints for the SOT-89-5 package. Confirm that the fixed 3.3 V output meets the target circuit requirements without external adjustment components.

Selection Notes

Select this component when a fixed 3.3 V output is required alongside integrated voltage detection. The SOT-89-5 package suits space-constrained surface-mount designs. Verify that the 1 A output current capability aligns with the load demands of the application circuit.

Part Context

This part belongs to the S-1701 series of high ripple-rejection low dropout CMOS voltage regulators. The series is characterized by the integration of voltage detectors and reset functions, distinguishing it from standard LDOs. It is designed for applications requiring reliable power management in compact form factors.

Replacement Considerations

Consult official ABLIC substitution guides for compatible alternatives. Verify pin-to-pin compatibility and electrical parameter alignment before replacing.
