S-1701Q1515-U5T1G

Overview

The S-1701Q1515-U5T1G is a low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It features a single fixed output of 1.5 V with a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and consumes a typical quiescent current of 85 µA. It provides high accuracy with a voltage regulation tolerance of 1%. The unit is housed in an SOT-89-5/6 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a voltage detector function alongside the linear regulator for system monitoring.
• Delivers stable regulated power with low quiescent current consumption for battery efficiency.
• Provides precise voltage regulation with tight tolerance accuracy.

Applications

• Battery-powered portable electronic devices
• Systems requiring combined voltage regulation and detection
• Low-power embedded circuits

Procurement Notes

Verify the specific package variant, as documentation indicates SOT-89-5 or SOT-89-6 configurations. Confirm RoHS compliance status through official manufacturer channels before procurement. Ensure the selected part matches the required output voltage and current specifications for your design. Check for any product change notifications that may affect pinouts or electrical characteristics.

Selection Notes

Select this component when a single 1.5 V rail is needed with integrated voltage supervision. It is suitable for applications prioritizing low standby current over high efficiency. Compare against other S-1701 series variants if different output voltages or multiple outputs are required. Ensure the input voltage remains within the specified 2 V to 6.5 V window for proper operation.

Part Context

This part belongs to the S-1701 series of LDO voltage regulators from ABLIC. The series is characterized by low quiescent current and integrated voltage detectors. Other models in the family offer various fixed output voltages and dual-output configurations, such as the S-1701Q1515-M5T1G which shares similar electrical parameters but may differ in packaging.

Replacement Considerations

The S-1701Q1515-M5T1G is a related model with identical electrical specifications. Verify package compatibility, as the M5T1G suffix typically denotes SOT-23-5 while the U5T1G denotes SOT-89-5/6. Direct substitution requires ensuring the physical footprint matches the PCB layout.
