S-1701V3325-M5T1G

Overview

The S-1701V3325-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC manufactured by ABLIC. It features a fixed 2.5 V output from the regulator and a 3.3 V detection threshold for the voltage monitor. The device operates with an input voltage range of 1.6 V to 6.5 V, delivering up to 400 mA output current. Key electrical parameters include a quiescent current of 85 µA, a dropout voltage of 140 mV at 100 mA, and line regulation of 0.2 %/V. It functions within a temperature range of -40°C to +85°C and is housed in an SOT-23-5 package.

Feature Summary

• Integrates a fixed-output LDO regulator with a dedicated voltage detector circuit in a single compact package.
• Provides ultra-low quiescent current consumption to extend battery life in portable applications.
• Ensures stable operation with low dropout voltage characteristics across the specified load range.

Applications

• Battery-powered portable electronic devices requiring efficient power management
• System supervision in mobile communication equipment
• Voltage monitoring in embedded control systems

Procurement Notes

Verify the specific output voltage and detection threshold against the datasheet before procurement, as suffixes define these critical parameters. Confirm the SOT-23-5 package compatibility with your PCB footprint. Ensure the operating temperature range meets your application requirements. Check for recent Product Change Notifications (PCN) regarding manufacturing updates. Validate RoHS compliance status if required by your supply chain standards.

Selection Notes

Select this component when a combined regulation and monitoring function is needed in a space-constrained design. The 400 mA output capability suits moderate load applications. Compare the 85 µA quiescent current against other LDOs to ensure optimal efficiency. Verify that the 2.5 V regulator output matches the load requirement and the 3.3 V detector threshold aligns with system supervision needs. Consider the SOT-23-5 package size relative to available board space.

FAQ

What is the difference between the regulator output and the detection threshold in this device?

The regulator provides a fixed 2.5 V output to power the load, while the voltage detector monitors the input or another rail and triggers an alert if it drops below or rises above the 3.3 V threshold.

Does the S-1701V3325-M5T1G support manual reset?

No, the S-1701 series typically does not include a manual reset pin; the voltage detector output changes state automatically based on the monitored voltage level.
