S-1701P1815-U5T1G

Overview

The S-1701P1815-U5T1G is a low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, designed for battery-powered applications. It features a single fixed output of 1.8 V with a maximum output current of 400 mA. The device integrates a voltage detector function and operates within an input voltage range supporting its regulation capabilities. Key electrical parameters include a quiescent current of 85 µA, a dropout voltage of 340 mV at specified loads, and line regulation of 0.2 %/V. It offers high voltage regulation accuracy of 1 % and supports a power dissipation of 1 W. The component functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates a voltage detector function alongside the LDO regulator for system monitoring.
• Optimized for low power consumption with an ultra-low quiescent current specification.
• Provides stable fixed voltage output suitable for sensitive digital logic circuits.
• Designed specifically for efficiency in battery-operated portable devices.

Applications

• Battery-powered consumer electronics
• Portable communication devices
• Embedded systems requiring voltage supervision

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct output voltage and package configuration. Confirm RoHS compliance status through the latest product change notifications or certification documents provided by ABLIC. Ensure that the ordering quantity aligns with the manufacturer's standard reel packaging requirements to avoid handling discrepancies during assembly.

Selection Notes

Select this component when a combined LDO regulator and voltage detector solution is required in a compact surface-mount package. Consider the 1.8 V fixed output and 400 mA current capability relative to the load requirements. Evaluate the thermal performance given the 1 W power dissipation limit in the SOT-89-5 package. Compare the 85 µA quiescent current against other regulators if extended battery life is a critical design constraint.

Part Context

This part belongs to the ABLIC S-1701 series of low-dropout regulators. These components are characterized by their integration of voltage detection functions, making them distinct from standard LDOs. The series targets applications where space constraints and power efficiency are paramount, utilizing small footprint packages like SOT-89-5 to facilitate dense PCB layouts in modern electronic designs.

Replacement Considerations

Consult ABLIC's official cross-reference documentation for verified substitutes. Ensure any replacement maintains the same output voltage, current rating, and package dimensions. Verify compatibility of the integrated voltage detector thresholds if that feature is utilized in the circuit design.
