S-1701C2520-U5T1G

Overview

The S-1701C2520-U5T1G is a low-dropout regulator from ABLIC featuring integrated voltage detection. It provides a fixed 2.5 V output with a maximum current of 400 mA and a typical quiescent current of 85 µA. The device operates within an input voltage range of 2 V to 6.5 V, utilizing an SOT-23-5 package. It maintains a voltage regulation accuracy of 1% and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Combines LDO regulation with voltage detection functionality in a single component
• Provides high output current capability of 400 mA for demanding loads
• Maintains low power consumption with minimal quiescent current draw
• Ensures stable performance through precise voltage regulation accuracy

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Embedded systems needing combined regulation and voltage monitoring

Procurement Notes

Verify the specific suffix U5T1G against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23-5 configuration. Cross-reference manufacturing dates and RoHS compliance status with current supplier documentation before finalizing orders.

Selection Notes

Select this component when both linear regulation and voltage threshold detection are required within limited board space. The 400 mA output capacity suits moderate load applications. Verify that the 2.5 V fixed output aligns with system logic levels. Consider the 85 µA standby current for battery life optimization in portable designs.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. The series integrates LDO functionality with voltage monitoring circuits. The C2520 designation indicates the specific 2.5 V output variant. The U5T1G suffix defines the surface-mount packaging and reel format for automated assembly processes.

Replacement Considerations

Direct substitutes include other S-1701 series variants with matching output voltages and package types.
