S-1701T2715-M5T1G

Overview

The S-1701T2715-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC manufactured by ABLIC Inc. It features two fixed output voltages: 1.5 V and 2.7 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 maintains a typical dropout voltage of 140 mV at full load. It incorporates a built-in voltage detector that monitors the main output, providing a reset signal when the voltage falls below a specified threshold. The IC is housed in a compact SOT-23-5 package and is designed for operation across a temperature range of -40°C to +85°C, ensuring stable performance in portable electronic applications requiring efficient power management and reliable system supervision.

Procurement Notes

Verify the exact part number S-1701T2715-M5T1G against official ABLIC documentation to confirm pinout compatibility and electrical specifications. Ensure that the required output voltages (1.5 V and 2.7 V) match your design needs. Check for any recent product change notifications (PCNs) that may affect packaging or manufacturing processes. Confirm availability through authorized distributors as lead times can vary. Validate thermal performance under your specific load conditions to ensure operation within the specified temperature range.

Selection Notes

Select this component when a combined LDO regulator and voltage detector solution is required in a small footprint. It is suitable for designs needing both 1.5 V and 2.7 V rails from a single input source between 2 V and 6.5 V. Consider its 400 mA output current capability and low dropout voltage for efficiency. Compare it with other S-1701 series variants if different output voltage combinations are needed. Ensure the SOT-23-5 package fits your PCB layout constraints.
