S-1701D2521-M5T1G

Overview

The S-1701D2521-M5T1G is a dual-output low dropout CMOS voltage regulator manufactured by ABLIC. It provides fixed output voltages of 2.5 V and 2.1 V with a maximum output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V and features a typical quiescent current of 85 µA. It utilizes an SOT-23-5 surface-mount package and supports an operating temperature range from -40 °C to +85 °C. The regulator includes integrated voltage detection functions for system monitoring.

Feature Summary

• Dual independent fixed voltage outputs for simultaneous power supply requirements
• Integrated voltage detector function for system supervision
• Low quiescent current consumption for battery-powered applications
• High ripple rejection ratio for noise-sensitive circuits

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-operated systems needing efficient power management
• Embedded controllers requiring integrated voltage supervision
• Consumer electronics with strict size constraints

Procurement Notes

Verify the specific suffix M5T1G against official ABLIC documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint, as the SOT-23-5 package dimensions are critical for assembly. Cross-reference the part number with the manufacturer's latest datasheet to confirm RoHS compliance and environmental certifications before finalizing procurement orders.

Selection Notes

Select this component when dual fixed outputs are required in a compact form factor. The 400 mA output current capability suits moderate load applications. Verify that the input voltage remains above the dropout threshold for both 2.5 V and 2.1 V outputs under all operating conditions. Consider thermal dissipation limits if operating near maximum current or high ambient temperatures.

Part Context

This part belongs to the S-1701 series of linear regulators designed for low-power applications. The series emphasizes low current consumption and small package sizes. The S-1701D variant specifically denotes the SOT-23-5 package configuration. This family is intended for portable electronics where space and power efficiency are primary design constraints.

Replacement Considerations

Check ABLIC's official substitution guide for equivalent parts with matching voltage outputs and package types. Verify pinout compatibility before replacing to avoid circuit damage. Ensure any substitute part meets the same electrical specifications and operating temperature range.
