S-1701W2522-M5T1G

Overview

The S-1701W2522-M5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, housed in an SOT-23-5 surface-mount package. It provides fixed output voltages of 2.2 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 µA and a maximum power dissipation of 1 W. It operates within a temperature range of -40°C to +85°C, offering a line regulation of 0.2%/V and a load regulation of 40 mV. The unit weighs approximately 30 mg.

Feature Summary

• Integrates two independent fixed-voltage LDO regulators within a single compact component
• Combines voltage regulation functionality with built-in voltage detection circuits
• Maintains stable performance with ultra-low quiescent current consumption

Applications

• Dual-rail power supply systems for embedded microcontrollers
• Voltage monitoring and reset generation in portable electronic devices
• Power management modules requiring simultaneous positive voltage rails

Procurement Notes

Verify the specific suffix against official ABLIC documentation to confirm pinout compatibility and exact voltage tolerances. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement contracts.

Selection Notes

Select this component when a design requires two distinct fixed voltage outputs from a single package footprint. The SOT-23-5 form factor suits space-constrained layouts. Verify that the required output currents do not exceed the 400 mA limit per channel under expected thermal conditions.

Part Context

This part belongs to the S-1701 family of combo voltage detectors and regulators. It shares the series' core architecture but differs in output voltage configuration and package type compared to other variants like the S-1701W2521-U5T1G which utilizes an SOT-89-5 package.

Replacement Considerations

Direct substitutes include other S-1701 series parts with identical SOT-23-5 packaging and matching output voltage pairs. Verify electrical parameters such as dropout voltage and quiescent current match the original design requirements.
