S-1701B2520-M5T1G

Overview

The S-1701B2520-M5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, manufactured by ABLIC Inc. It provides fixed output voltages of 2.0 V and 2.5 V with a maximum output current of 400 mA per channel. The device features an ultra-low quiescent current of 85 µA and operates within an input voltage range of 2 V to 6.5 V. It is housed in a compact SOT-23-5 surface-mount package and supports a wide operating temperature range from -40°C to +85°C. The regulator includes integrated voltage detection functionality for system monitoring.

Feature Summary

• Dual fixed output channels providing independent regulated voltages
• Ultra-low quiescent current consumption for battery efficiency
• Integrated voltage detector for system status monitoring
• Compact SOT-23-5 package for space-constrained designs

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems needing low standby current
• Embedded controllers requiring integrated voltage supervision
• Automotive infotainment and sensor modules

Procurement Notes

Verify the specific output voltage combination and package type against your schematic requirements before ordering. Confirm that the SOT-23-5 footprint matches your PCB layout. Check for any recent Product Change Notifications (PCNs) regarding pinout or material changes. Ensure the operating temperature range meets your environmental specifications. Validate compatibility with your system's voltage detection thresholds.

Selection Notes

Select this component when dual isolated outputs are required from a single LDO structure. The 85 µA quiescent current makes it suitable for always-on applications. Compare dropout voltage characteristics at your expected load current against alternative regulators. Consider the thermal dissipation capabilities of the SOT-23-5 package under your specific power conditions. Verify that the 400 mA output current meets the peak demand of your connected loads.

Part Context

This part belongs to the ABLIC S-1701 series of combo voltage detectors and regulators. The series is designed for automotive and industrial applications requiring high reliability and low power consumption. Similar parts in the series vary by output voltage combinations and package options, such as SOT-89-5. The M5 suffix typically indicates the SOT-23-5 package variant.

Replacement Considerations

Direct replacements include other S-1701 series variants with matching output voltages and packages, such as S-1701W2521-U5T1G or S-1701N1827-M5T1G, depending on the required voltage levels. Ensure pin compatibility and electrical specifications match before substitution.
