S-1701B3025-M5T1G

Overview

The S-1701B3025-M5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, manufactured by ABLIC Inc. It integrates two fixed output voltages of 2.5 V and 3.0 V within a single package. The device supports a maximum output current of 400 mA per channel with a typical quiescent current of 85 µA. It operates within an input voltage range of 2 V to 6.5 V and features a dropout voltage of approximately 140 mV at 100 mA. The component provides high voltage regulation accuracy of 1% and includes built-in voltage detection functions. It is housed in a compact SOT-23-5 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Dual fixed output channels providing 2.5 V and 3.0 V simultaneously
• Integrated voltage detector function for system monitoring
• Low quiescent current consumption of 85 µA for power efficiency
• High precision voltage regulation with 1% accuracy

Applications

• Portable electronic devices requiring multiple stable supply rails
• Battery-powered systems needing efficient power management
• Embedded circuits utilizing integrated voltage supervision
• Compact consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix M5T1G corresponds to the SOT-23-5 package configuration as indicated by the model structure. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration. Ensure input voltage constraints are strictly observed to maintain regulation accuracy and prevent thermal issues within the specified operating temperature range.

Selection Notes

Select this component when dual independent regulated outputs are required from a single source to reduce board space. The 400 mA output capability suits moderate load applications. Compare dropout characteristics against other LDOs if input-to-output differential is minimal. Verify that the integrated voltage detector thresholds meet system reset or monitoring requirements without external components.

Part Context

This part belongs to the ABLIC S-1701 series of combo voltage detectors and regulators. These devices combine linear regulation with voltage monitoring capabilities in a small footprint. The series is designed for battery-operated equipment where low standby current and precise voltage control are critical. The S-1701B variant specifically denotes the dual-output configuration with fixed voltage settings.

Replacement Considerations

Direct substitutes include other S-1701 series parts with compatible pinouts and similar output voltages, such as S-1701N3315-M5T1G for different voltage pairs. Cross-reference pin configurations carefully as package variations exist within the series. Ensure replacement parts maintain the same quiescent current and regulatory accuracy specifications.
