S-1701E2522-U5T1G

Overview

The S-1701E2522-U5T1G is a dual-output low-dropout regulator from the ABLIC S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 2.2 V and 2.5 V with a combined maximum output current of 400 mA. The device features a typical quiescent current of 85 µA and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a dropout voltage of 160 mV, line regulation of 0.2% per V, load regulation of 40 mV, and power dissipation capability of 1 W.

Feature Summary

• Dual-output configuration providing two independent fixed voltage rails
• Ultra-low quiescent current for extended battery life
• High output current capability up to 400 mA
• Integrated voltage detection functionality

Applications

• Portable electronic devices requiring multiple voltage domains
• Battery-powered systems prioritizing power efficiency
• Embedded circuits needing stable dual-rail power supplies
• Voltage detection and regulation in compact form factors

Procurement Notes

Verify the specific part number against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure that the required output voltages (2.2 V and 2.5 V) match the target application design. Check for any recent product change notifications or obsolescence announcements directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a dual-output LDO with low standby current is required in a small SOT-89-5 package. Consider the 400 mA total current limit and the specific 2.2 V/2.5 V output combination. Evaluate the thermal performance given the 1 W power dissipation rating and the operating temperature range of -40°C to +85°C for the intended environment.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs by ABLIC Inc. The series is characterized by low quiescent current and high output current capabilities, designed for space-constrained applications. The S-1701E2522-U5T1G specifically offers dual fixed outputs, distinguishing it from single-output variants within the same family.

Replacement Considerations

Check for direct substitutes within the S-1701 series offering different voltage combinations but identical pinouts and current ratings. Verify compatibility with existing PCB layouts and thermal management strategies if considering alternative packages or manufacturers.
