S-1701F3025-M5T1G

Overview

The S-1701F3025-M5T1G is a low-dropout voltage regulator from the S-1701 series by ABLIC, housed in an SOT-23-5 package. It integrates two fixed positive output channels providing 2.5 V and 3.0 V, with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 140 mV. It operates within a temperature range of -40°C to +85°C and includes built-in voltage detection functionality for system monitoring.

Feature Summary

• Integrates dual fixed-output LDO regulators with combined voltage detection capabilities
• Provides high output current capacity of 400 mA for powering load circuits
• Maintains ultra-low standby current consumption for extended battery life
• Ensures stable regulation with minimal voltage drop under load conditions

Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing low quiescent current operation
• Embedded circuits requiring simultaneous multiple voltage rails
• Mobile communication modules with strict power constraints

Procurement Notes

Verify the complete part number including the suffix M5T1G to ensure correct packaging and tape-and-reel configuration. Confirm that the required output voltages (2.5 V and 3.0 V) match the specific application needs, as these are fixed values. Check the thermal requirements for the SOT-23-5 package in the final design layout. Ensure compliance with RoHS directives if applicable to the target market.

Selection Notes

Select this component when dual voltage rails are needed from a single IC to save board space. The 400 mA output capability suits moderate load applications. Consider the 85 µA quiescent current for battery-powered designs. Verify that the input voltage range supports the required outputs with the specified dropout voltage. Compare against other S-1701 variants if different voltage combinations are required.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. It shares the same package and basic electrical characteristics with other variants in the family, differing primarily in the fixed output voltage levels. The series is designed for portable equipment where space and power efficiency are critical. Other models may offer different voltage pairs or slightly varied dropout characteristics.

Replacement Considerations

Direct substitutes within the S-1701 series include parts with identical pinouts and similar electrical specs but different output voltages, such as S-1701F2722-M5T1G or S-1701F2519-M5T1G, provided the voltage difference is acceptable for the circuit design. Cross-family replacements require careful verification of pin compatibility and thermal performance.
