S-1701F2521-M5T1G

Overview

The S-1701F2521-M5T1G is a low dropout CMOS voltage regulator with an integrated reset function, manufactured by ABLIC. It operates within an input voltage range of 2 V to 6.5 V and delivers a fixed output voltage of 2.1 V at up to 400 mA. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 140 mV at full load. It provides high ripple rejection and maintains line regulation of 0.2 %/V and load regulation of 40 mV. Designed for surface mount applications in the SOT-23-5 package, it supports operating temperatures from -40 °C to +85 °C.

Feature Summary

• Integrates a low dropout voltage regulator with a built-in reset function for system monitoring.
• Delivers high output current capability of 400 mA with low quiescent current consumption.
• Ensures stable power supply performance through high ripple rejection ratios.

Applications

• Power management for portable electronic devices requiring compact regulators
• Voltage regulation for microcontroller systems with reset requirements
• Battery-powered equipment needing efficient low-dropout conversion

Procurement Notes

Verify the specific suffix M5T1G against the manufacturer's official datasheet to confirm pin configuration and tape-and-reel specifications. Ensure compatibility with the required output voltage and thermal dissipation limits for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a combined LDO and reset signal is required in a small footprint. Compare the 2.1 V fixed output against system rail requirements. Evaluate the 400 mA current limit against peak load demands and verify that the SOT-23-5 package meets the board space constraints.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. It shares the family's core architecture of high accuracy and low current consumption but is distinguished by its specific 2.1 V output setting and integrated reset threshold functionality compared to other variants in the lineup.

Replacement Considerations

Direct substitutes include other S-1701 series parts with identical SOT-23-5 packaging and matching output voltages, such as the S-1701D2521-M5T1X or similar ABLIC LDOs with reset functions. Verify electrical parameters match exactly before substitution.
