S-1701P2515-U5T1G

Overview

The S-1701P2515-U5T1G is a CMOS-based low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, integrating a fixed 2.5 V output with a high-accuracy voltage detector. It delivers up to 400 mA output current with an input voltage range of 2 V to 6.5 V. Key electrical parameters include a typical quiescent current of 85 µA, a maximum dropout voltage of 380 mV at 100 mA, and a line regulation of 0.2 %/V. The device operates within a temperature range of -40 °C to +85 °C and features a 1 % output voltage accuracy.

Feature Summary

• Integrates a high-accuracy voltage detector with a reset function for system monitoring
• Provides stable regulation with low quiescent current consumption suitable for battery-powered applications
• Features a compact SOT-89-5 surface-mount package design

Applications

• Battery-powered electronic devices requiring efficient power management
• Systems utilizing voltage detectors for supervisory control
• Portable consumer electronics needing compact LDO solutions

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required tape-and-reel packaging configuration. Confirm that the integrated voltage detector threshold aligns with your system's reset requirements. Ensure thermal dissipation calculations account for the SOT-89-5 package limitations under maximum load conditions. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or pinout definitions prior to ordering.

Selection Notes

Select this component when a fixed 2.5 V output is required alongside voltage supervision capabilities. The 400 mA current rating supports moderate load demands while maintaining low standby current. Consider the 380 mV dropout voltage for headroom requirements relative to the minimum input voltage. The SOT-89-5 footprint is appropriate for space-constrained PCB layouts compared to larger packages.

Part Context

This part belongs to the ABLIC S-1701 series, which combines LDO regulators with voltage detectors. The series utilizes CMOS technology to achieve low power consumption. The S-1701P2515 variant specifically denotes the 2.5 V output version within the broader family of adjustable and fixed voltage options available in the product line.

Replacement Considerations

Direct substitutes within the same series include other S-1701 variants with different output voltages but identical package and functional characteristics. Verify compatibility by comparing the output voltage, current capacity, and detector thresholds against the original design specifications.
