S-1701P2715-U5T1G

Overview

The S-1701P2715-U5T1G is a dual-output low dropout (LDO) voltage regulator manufactured by ABLIC Inc. It integrates two fixed output channels providing 1.5 V and 2.7 V within a single SOT-89-5 package. The device supports a maximum output current of 400 mA per channel with an ultra-low quiescent current of 85 uA. It features a typical dropout voltage of 340 mV at 100 mA, ensuring efficient power management in battery-powered applications. The component operates reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture combining two independent LDO regulators in one compact package
• Ultra-low quiescent current consumption for extended battery life in portable devices
• Integrated voltage detection functionality for system supervision
• High precision fixed output voltages with stable regulation under varying load conditions

Applications

• Battery-operated mobile communication devices requiring multiple voltage rails
• Portable consumer electronics needing space-efficient power management solutions
• Embedded systems utilizing voltage detectors for supervisory control
• IoT sensors and modules demanding low standby current consumption

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 surface mount package configuration. Confirm that the dual output combination matches the required 1.5 V and 2.7 V levels for your circuit design. Ensure compatibility with the specified operating temperature range and input voltage constraints defined in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a dual-rail power supply solution is required within strict spatial constraints. The S-1701 series offers high integration by combining regulation and detection functions. Consider the 400 mA output capability and 85 uA quiescent current as key differentiators for efficiency-sensitive designs. Validate thermal performance requirements given the SOT-89-5 package power dissipation characteristics.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs from ABLIC. The series is designed for applications requiring both power regulation and voltage monitoring in a minimal footprint. The S-1701P2715 variant specifically provides the 1.5 V and 2.7 V output combination, distinguishing it from other models in the family that offer different voltage pairs or single outputs.

Replacement Considerations

Direct substitutes include other S-1701 series variants with identical pinout and package but different output voltages if electrical parameters differ. Cross-reference with similar dual-output LDOs from ABLIC such as the S-1701U1815-M5T1G for alternative voltage combinations in the same package family.
