S-1701Q2515-U5T1G

Overview

The S-1701Q2515-U5T1G is a low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, integrating a high-accuracy voltage detector. It provides two fixed output voltages: 1.5 V and 2.5 V. The device supports a maximum output current of 400 mA with a typical quiescent current of 85 µA. It operates within an input voltage range of 1.6 V to 3.6 V and features a maximum dropout voltage of 160 mV at full load. The component is housed in an SOT-23-5 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates a high-accuracy voltage detector with a reset function for system monitoring
• Provides dual fixed output voltages (1.5 V and 2.5 V) from a single LDO regulator
• Features ultra-low quiescent current consumption for battery-powered applications
• Operates with a wide input voltage range up to 3.6 V

Applications

• Battery-powered portable electronic devices
• Voltage regulation for microcontrollers requiring multiple supply rails
• System reset monitoring in embedded circuits
• Power management in consumer electronics

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-23-5 package and reel packaging configuration as listed by authorized distributors. Confirm that the dual-output variant matches the design requirements for both 1.5 V and 2.5 V rails simultaneously. Ensure compatibility with the target operating temperature range of -40°C to +85°C for the intended application environment.

Selection Notes

Select this component when a single IC solution is needed to provide both regulated power and voltage supervision. The dual-output capability eliminates the need for separate regulators for different logic levels. Consider the 400 mA current limit and 160 mV dropout voltage against the load requirements and available input voltage headroom. The low 85 µA IQ makes it suitable for energy-efficient designs compared to standard LDOs.

Part Context

This part belongs to the ABLIC S-1701 series, which combines CMOS LDO technology with voltage detection functions. Unlike single-output regulators, this specific model offers two distinct fixed outputs, simplifying board space and component count. It is designed for applications requiring stable power delivery alongside precise voltage monitoring for system integrity.

Replacement Considerations

Direct replacements must match the dual-output specification (1.5 V/2.5 V), SOT-23-5 package, and similar electrical characteristics. Verify that any substitute maintains the same quiescent current profile and reset threshold accuracy. Cross-reference pinouts to ensure compatibility without circuit redesign.
