S-1701D2520-M5T1G

Overview

The S-1701D2520-M5T1G is a dual-output low dropout (LDO) voltage regulator from ABLIC's S-1701 series, housed in an SOT-23-5 surface-mount package. It provides fixed output voltages of 2.0 V and 2.5 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 uA and a maximum power dissipation of 420 mW. Operating specifications include a minimum input voltage of 2 V, a maximum input voltage of 6.5 V, and a functional temperature range from -40°C to +85°C.

Feature Summary

• Integrates two independent linear regulators within a single compact package for space-constrained designs.
• Incorporates built-in voltage detection functions to monitor supply levels and ensure system reliability.
• Delivers stable regulation with low dropout characteristics suitable for battery-powered applications.

Applications

• Dual-rail power distribution in portable electronic devices.
• Voltage regulation for microcontrollers requiring multiple logic levels.
• Power management circuits in consumer electronics and IoT modules.

Procurement Notes

Verify the specific suffix M5T1G against official ABLIC documentation to confirm the exact tape-and-reel packaging configuration and pin assignment. Ensure that the selected component matches the required thermal performance for the intended application environment. Cross-reference the datasheet for any recent product change notifications or obsolescence announcements prior to finalizing procurement orders.

Selection Notes

Select this component when a design requires two distinct fixed voltage rails from a single regulator unit. The SOT-23-5 package offers a small footprint compared to larger alternatives. Consider the 420 mW power dissipation limit relative to ambient temperature and board layout. Verify that the input voltage range supports the system's source voltage under all operating conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs. These components are designed to provide efficient power management by combining regulation with monitoring capabilities. The series targets applications where size reduction and power efficiency are critical, offering a consolidated solution for multi-voltage systems without requiring separate discrete regulators.

Replacement Considerations

Direct substitutes may include other S-1701 variants with different output voltages but identical packages, such as S-1701D2521-M5T1G. Verify compatibility by comparing pinouts, electrical parameters, and thermal characteristics. Consult the manufacturer's cross-reference guide for officially confirmed replacement part numbers.
